Hi @Joe Gaffney. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To handle error responses in your axios instance and ensure that the error message is extracted correctly, you can use the following code snippet. This code sets up an axios instance with an interceptor that transforms the error response to include a custom error message and status code. Here is the code you can use:

import { HttpError } from "@refinedev/core";
import axios from "axios";

const axiosInstance = axios.create();

axiosInstance.interceptors.response.use(
  (response) => {
    return response;
  },
  (error) => {
    const customError: HttpError = {
      ...error,
      message: error.response?.data?.message,
      statusCode: error.response?.status,
    };

    return Promise.reject(customError);
  }
);

export { axiosInstance };

import { HttpError } from "@refinedev/core";
import axios from "axios";

const axiosInstance = axios.create();

axiosInstance.interceptors.response.use(
  (response) => {
    return response;
  },
  (error) => {
    const customError: HttpError = {
      ...error,
      message: error.response?.data?.message,
      statusCode: error.response?.status,
    };

    return Promise.reject(customError);
  }
);

export { axiosInstance };

This code ensures that when an error occurs, the axios interceptor will capture the error response, extract the message and status code, and then reject the promise with a custom error object that conforms to the HttpError interface expected by Refine. For more details on error handling in Refine, you can refer to the Error Format section of the Data Provider documentation (https://refine.dev/docs/data/data-provider#error-format). If you need further customization or have additional questions, you might find the following resources helpful: - Data Provider documentation (https://refine.dev/docs/data/data-provider/) - Handling errors with notificationProvider (https://refine.dev/docs/guides-concepts/data-fetching/#handling-errors) Feel free to ask if you have more questions or need further assistance! ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I am doing it this way but does not seem to be automatically passed to the notifiaction provider that way for the on notitifcations

kapa.ai•2mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To ensure that the custom error messages are automatically passed to the notificationProvider in Refine, you need to make sure that your notificationProvider is correctly set up and that the errors thrown by your axios instance are in the format expected by Refine. Here is a step-by-step guide to achieve this: 1. Set up the axios instance with custom error handling:

    import { HttpError } from "@refinedev/core";
    import axios from "axios";

    const axiosInstance = axios.create();

    axiosInstance.interceptors.response.use(
      (response) => {
        return response;
      },
      (error) => {
        const customError: HttpError = {
          ...error,
          message: error.response?.data?.message,
          statusCode: error.response?.status,
        };

        return Promise.reject(customError);
      }
    );

    export { axiosInstance };

    import { HttpError } from "@refinedev/core";
    import axios from "axios";

    const axiosInstance = axios.create();

    axiosInstance.interceptors.response.use(
      (response) => {
        return response;
      },
      (error) => {
        const customError: HttpError = {
          ...error,
          message: error.response?.data?.message,
          statusCode: error.response?.status,
        };

        return Promise.reject(customError);
      }
    );

    export { axiosInstance };

2. Ensure your notificationProvider is set up in your Refine configuration:

    import { Refine } from "@refinedev/core";
    import { notificationProvider } from "@refinedev/antd"; // or any other UI framework you are using

    const App = () => {
      return (
        <Refine
          notificationProvider={notificationProvider}
          // other props
        />
      );
    };

    export default App;

    import { Refine } from "@refinedev/core";
    import { notificationProvider } from "@refinedev/antd"; // or any other UI framework you are using

    const App = () => {
      return (
        <Refine
          notificationProvider={notificationProvider}
          // other props
        />
      );
    };

    export default App;

3. Customize the error notification if needed: If you need to customize the error notification, you can use the errorNotification prop in your hooks. Here is an example using the useShow hook:

    import { useShow } from "@refinedev/core";
const MyComponent = () => {
      const { queryResult } = useShow({
        resource: "posts",
        id: 1,
        errorNotification: (error) => {
          return {
            message: `Error: ${error.message}`,
            description: `Status Code: ${error.statusCode}`,
            type: "error",
          };
        },
      });

      // component logic
    };

    import { useShow } from "@refinedev/core";
const MyComponent = () => {
      const { queryResult } = useShow({
        resource: "posts",
        id: 1,
        errorNotification: (error) => {
          return {
            message: `Error: ${error.message}`,
            description: `Status Code: ${error.statusCode}`,
            type: "error",
          };
        },
      });

      // component logic
    };

By following these steps, you ensure that the custom error messages from your axios instance are correctly passed to the notificationProvider and displayed to the user. For more details, you can refer to the following documentation: - Notification Provider (https://refine.dev/docs/notification/notification-provider/) - Handling Errors (https://refine.dev/docs/guides-concepts/data-fetching#handling-errors) If you have any further questions or need additional assistance, feel free to ask! ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I have the useNotificaitonProvider set up and know i can manually dig through the response for the message. But can't understand why it it not propergating the message up

kapa.ai•2mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To ensure that the error messages from your axios instance are properly propagated to the notificationProvider, you need to make sure that the custom error object is correctly formatted and that the notificationProvider is set up to handle these errors. Here are the steps to troubleshoot and ensure proper propagation: 1. Ensure Custom Error Object is Correctly Formatted: Make sure your axios interceptor is correctly formatting the error object. The HttpError interface should include the message and statusCode properties.

    import { HttpError } from "@refinedev/core";
    import axios from "axios";

    const axiosInstance = axios.create();

    axiosInstance.interceptors.response.use(
      (response) => {
        return response;
      },
      (error) => {
        const customError: HttpError = {
          ...error,
          message: error.response?.data?.message,
          statusCode: error.response?.status,
        };

        return Promise.reject(customError);
      }
    );

    export { axiosInstance };

    import { HttpError } from "@refinedev/core";
    import axios from "axios";

    const axiosInstance = axios.create();

    axiosInstance.interceptors.response.use(
      (response) => {
        return response;
      },
      (error) => {
        const customError: HttpError = {
          ...error,
          message: error.response?.data?.message,
          statusCode: error.response?.status,
        };

        return Promise.reject(customError);
      }
    );

    export { axiosInstance };

2. Set Up notificationProvider in Refine Configuration: Ensure that the notificationProvider is correctly set up in your Refine configuration. This will allow Refine to use the notification system to display errors.

    import { Refine } from "@refinedev/core";
    import { useNotificationProvider } from "@refinedev/antd"; // or any other UI framework you are using
    import { ConfigProvider, App as AntdApp } from "antd";

    const App = () => {
      return (
        <ConfigProvider theme={RefineThemes.Blue}>
          <AntdApp>
            <Refine
              notificationProvider={useNotificationProvider}
              // other props
            />
          </AntdApp>
        </ConfigProvider>
      );
    };

    export default App;

    import { Refine } from "@refinedev/core";
    import { useNotificationProvider } from "@refinedev/antd"; // or any other UI framework you are using
    import { ConfigProvider, App as AntdApp } from "antd";

    const App = () => {
      return (
        <ConfigProvider theme={RefineThemes.Blue}>
          <AntdApp>
            <Refine
              notificationProvider={useNotificationProvider}
              // other props
            />
          </AntdApp>
        </ConfigProvider>
      );
    };

    export default App;

3. Customize Error Notification Handling: If you need to customize how errors are displayed, you can use the errorNotification prop in your hooks. This ensures that the error message and status code are displayed correctly.

    import { useShow } from "@refinedev/core";

    const MyComponent = () => {
      const { queryResult } = useShow({
        resource: "posts",
        id: 1,
        errorNotification: (error) => {
          return {
            message: `Error: ${error.message}`,
            description: `Status Code: ${error.statusCode}`,
            type: "error",
          };
        },
      });

      // component logic
    };

    import { useShow } from "@refinedev/core";

    const MyComponent = () => {
      const { queryResult } = useShow({
        resource: "posts",
        id: 1,
        errorNotification: (error) => {
          return {
            message: `Error: ${error.message}`,
            description: `Status Code: ${error.statusCode}`,
            type: "error",
          };
        },
      });

      // component logic
    };

4. Verify Notification Provider Compatibility with Theme: Ensure that the notificationProvider is compatible with the current theme context. This can be done by wrapping your app with the App component from antd and using the useNotificationProvider export from @refinedev/antd.

    import { Refine } from "@refinedev/core";
    import { ThemedLayoutV2, useNotificationProvider } from "@refinedev/antd";
    import { ConfigProvider, App as AntdApp } from "antd";

    const App: React.FC = () => {
      return (
        <ConfigProvider theme={RefineThemes.Blue}>
          <AntdApp>
            <Refine
              notificationProvider={useNotificationProvider}
              // other props
            >
              <ThemedLayoutV2>{/* ... */}</ThemedLayoutV2>
            </Refine>
          </AntdApp>
        </ConfigProvider>
      );
    };

    export default App;

    import { Refine } from "@refinedev/core";
    import { ThemedLayoutV2, useNotificationProvider } from "@refinedev/antd";
    import { ConfigProvider, App as AntdApp } from "antd";

    const App: React.FC = () => {
      return (
        <ConfigProvider theme={RefineThemes.Blue}>
          <AntdApp>
            <Refine
              notificationProvider={useNotificationProvider}
              // other props
            >
              <ThemedLayoutV2>{/* ... */}</ThemedLayoutV2>
            </Refine>
          </AntdApp>
        </ConfigProvider>
      );
    };

    export default App;

By following these steps, you should be able to ensure ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I think its more the interceptor is not getting the error message form the responce data. It is getting the status code.

kapa.ai•2mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If the interceptor is correctly getting the status code but not the error message from the response data, it might be due to the structure of the error response. You need to ensure that the error response structure is correctly accessed in the interceptor. Here is a refined version of the interceptor to handle different possible structures of the error response:

import { HttpError } from "@refinedev/core";
import axios from "axios";

const axiosInstance = axios.create();

axiosInstance.interceptors.response.use(
  (response) => {
    return response;
  },
  (error) => {
    // Check if the error response has the expected structure
    const message = error.response?.data?.message || error.message || "An unknown error occurred";
    const statusCode = error.response?.status || 500;

    const customError: HttpError = {
      ...error,
      message,
      statusCode,
    };

    return Promise.reject(customError);
  }
);

export { axiosInstance };

import { HttpError } from "@refinedev/core";
import axios from "axios";

const axiosInstance = axios.create();

axiosInstance.interceptors.response.use(
  (response) => {
    return response;
  },
  (error) => {
    // Check if the error response has the expected structure
    const message = error.response?.data?.message || error.message || "An unknown error occurred";
    const statusCode = error.response?.status || 500;

    const customError: HttpError = {
      ...error,
      message,
      statusCode,
    };

    return Promise.reject(customError);
  }
);

export { axiosInstance };

Explanation: 1. Error Message Extraction: - The interceptor first tries to get the error message from error.response?.data?.message. - If that is not available, it falls back to error.message. - If neither is available, it defaults to "An unknown error occurred". 2. Status Code Extraction: - The status code is extracted from error.response?.status. - If the status code is not available, it defaults to 500. Additional Steps: - Ensure the API Response Structure: Make sure that your API is returning error responses with a message field in the data object. For example:

  {
    "data": null,
    "error": {
      "status": 400,
      "name": "ApplicationError",
      "message": "Email already taken",
      "details": {}
    }
  }

  {
    "data": null,
    "error": {
      "status": 400,
      "name": "ApplicationError",
      "message": "Email already taken",
      "details": {}
    }
  }

- Verify the Notification Provider Setup: Ensure that your notificationProvider is correctly set up to display the error messages. You can refer to the Notification Provider documentation (https://refine.dev/docs/notification/notification-provider/) for more details. By following these steps and using the refined interceptor, you should be able to correctly extract and propagate the error message from the response data to the notificationProvider. If you continue to face issues, you might want to log the entire error response to debug further:

axiosInstance.interceptors.response.use(
  (response) => {
    return response;
  },
  (error) => {
    console.error("Error response:", error.response);
    const message = error.response?.data?.message || error.message || "An unknown error occurred";
    const statusCode = error.response?.status || 500;

    const customError: HttpError = {
      ...error,
      message,
      statusCode,
    };

    return Promise.reject(customError);
  }
);

axiosInstance.interceptors.response.use(
  (response) => {
    return response;
  },
  (error) => {
    console.error("Error response:", error.response);
    const message = error.response?.data?.message || error.message || "An unknown error occurred";
    const statusCode = error.response?.status || 500;

    const customError: HttpError = {
      ...error,
      message,
      statusCode,
    };

    return Promise.reject(customError);
  }
);

This will help you understand the exact structure of the error response and adjust the interceptor accordingly. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai its like it does nto reach the error part of the interceptor

kapa.ai•2mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If the error part of the interceptor is not being reached, it might be due to the way the error is being thrown or handled before it reaches the interceptor. Here are a few steps to troubleshoot and ensure that the error interceptor is correctly set up and being triggered: 1. Ensure Axios Instance is Used: Make sure that the axiosInstance you created is the one being used for all your API requests. 2. Check for Network Errors: Network errors (like DNS issues) might not have a response object. Ensure that your interceptor handles such cases. 3. Log the Error: Add logging to see if the error is being caught by the interceptor. Here is a refined version of the interceptor with additional logging:

import { HttpError } from "@refinedev/core";
import axios from "axios";

const axiosInstance = axios.create();

axiosInstance.interceptors.response.use(
  (response) => {
    return response;
  },
  (error) => {
    console.error("Interceptor caught an error:", error);

    // Check if the error response has the expected structure
    const message = error.response?.data?.message || error.message || "An unknown error occurred";
    const statusCode = error.response?.status || 500;

    const customError: HttpError = {
      ...error,
      message,
      statusCode,
    };

    return Promise.reject(customError);
  }
);

export { axiosInstance };

import { HttpError } from "@refinedev/core";
import axios from "axios";

const axiosInstance = axios.create();

axiosInstance.interceptors.response.use(
  (response) => {
    return response;
  },
  (error) => {
    console.error("Interceptor caught an error:", error);

    // Check if the error response has the expected structure
    const message = error.response?.data?.message || error.message || "An unknown error occurred";
    const statusCode = error.response?.status || 500;

    const customError: HttpError = {
      ...error,
      message,
      statusCode,
    };

    return Promise.reject(customError);
  }
);

export { axiosInstance };

Steps to Ensure Proper Error Handling: 1. Use the Axios Instance: Ensure that all your API requests are using the axiosInstance you exported.

   import { axiosInstance } from "./path-to-axios-instance";
const fetchData = async () => {
     try {
       const response = await axiosInstance.get("/your-api-endpoint");
       console.log(response.data);
     } catch (error) {
       console.error("Error during API call:", error);
     }
   };

   fetchData();

   import { axiosInstance } from "./path-to-axios-instance";
const fetchData = async () => {
     try {
       const response = await axiosInstance.get("/your-api-endpoint");
       console.log(response.data);
     } catch (error) {
       console.error("Error during API call:", error);
     }
   };

   fetchData();

2. Check API Response Structure: Ensure that your API is returning errors in a structure that includes a message field in the data object. 3. Verify Notification Provider Setup: Ensure that your notificationProvider is correctly set up to display the error messages. You can refer to the Notification Provider documentation (https://refine.dev/docs/notification/notification-provider/) for more details. By following these steps and using the refined interceptor, you should be able to correctly capture and handle errors in your application. If the issue persists, the logging added to the interceptor should help you identify why the error part is not being reached. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai does it matter what error code i am using i am using 401 Im notcing my auth provider onError message also gets trigger could thisbe something to do with it onError: async (error) => { console.error(error); return { error }; }, };

kapa.ai•2mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, the error code you are using can affect how the authProvider's onError method is triggered. In Refine, certain HTTP status codes like 401 (Unauthorized) and 403 (Forbidden) are commonly used to trigger authentication-related error handling, such as logging out the user or redirecting them to a login page. If your authProvider's onError method is being triggered, it could be due to the 401 status code. Here is an example of how the onError method might be set up to handle such status codes:

import type { AuthProvider } from "@refinedev/core";

const authProvider: AuthProvider = {  
  // Other methods...

  onError: async (error) => {  
    console.error(error);
    if (error.status === 401 || error.status === 403) {  
      return {  
        logout: true,  
        redirectTo: "/login",  
        error,  
      };  
    }  
    return { error };  
  },
  
  // Other methods...
};

import type { AuthProvider } from "@refinedev/core";

const authProvider: AuthProvider = {  
  // Other methods...

  onError: async (error) => {  
    console.error(error);
    if (error.status === 401 || error.status === 403) {  
      return {  
        logout: true,  
        redirectTo: "/login",  
        error,  
      };  
    }  
    return { error };  
  },
  
  // Other methods...
};

Explanation: - Error Handling in authProvider: - The onError method checks if the error status is 401 or 403. - If it is, it returns an object that includes logout: true and redirectTo: "/login", which will log out the user and redirect them to the login page. - For other errors, it simply returns the error object. Steps to Ensure Proper Error Handling: 1. Ensure Custom Error Object is Correctly Formatted: Make sure your axios interceptor is correctly formatting the error object.

   import { HttpError } from "@refinedev/core";
   import axios from "axios";

   const axiosInstance = axios.create();

   axiosInstance.interceptors.response.use(
     (response) => {
       return response;
     },
     (error) => {
       console.error("Interceptor caught an error:", error);
const message = error.response?.data?.message || error.message || "An unknown error occurred";
       const statusCode = error.response?.status || 500;

       const customError: HttpError = {
         ...error,
         message,
         statusCode,
       };

       return Promise.reject(customError);
     }
   );

   export { axiosInstance };

   import { HttpError } from "@refinedev/core";
   import axios from "axios";

   const axiosInstance = axios.create();

   axiosInstance.interceptors.response.use(
     (response) => {
       return response;
     },
     (error) => {
       console.error("Interceptor caught an error:", error);
const message = error.response?.data?.message || error.message || "An unknown error occurred";
       const statusCode = error.response?.status || 500;

       const customError: HttpError = {
         ...error,
         message,
         statusCode,
       };

       return Promise.reject(customError);
     }
   );

   export { axiosInstance };

2. Use the Axios Instance: Ensure that all your API requests are using the axiosInstance you exported.

   import { axiosInstance } from "./path-to-axios-instance";

   const fetchData = async () => {
     try {
       const response = await axiosInstance.get("/your-api-endpoint");
       console.log(response.data);
     } catch (error) {
       console.error("Error during API call:", error);
     }
   };

   fetchData();

   import { axiosInstance } from "./path-to-axios-instance";

   const fetchData = async () => {
     try {
       const response = await axiosInstance.get("/your-api-endpoint");
       console.log(response.data);
     } catch (error) {
       console.error("Error during API call:", error);
     }
   };

   fetchData();

3. Verify Notification Provider Setup: Ensure that your notificationProvider is correctly set up to display the error messages. You can refer to the Notification Provider documentation (https://refine.dev/docs/notification/notification-provider/) for more details. By following these steps, you should be able to correctly capture and handle errors in your application, ensuring that the authProvider's onError method is triggered appropriately based on the error status code. If you continue to face issues, the logging added to the interceptor and onError method should help you debug further. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai so issue was i was making my own axiosInstance in App.tsx importing this fixed to pick up the one from the date provider import { axiosInstance } from "./rest-data-provider/utils";

Let me check the knowledge base for you. One moment! :books: ---------------------- It looks like the issue was due to creating a separate axiosInstance in App.tsx instead of using the one from your rest-data-provider. Importing the axiosInstance from the correct module fixed the issue. Here is how you can ensure that you are using the correct axiosInstance: 1. Create and Export axiosInstance in rest-data-provider/utils:

    // rest-data-provider/utils.ts
    import { HttpError } from "@refinedev/core";
    import axios from "axios";

    const axiosInstance = axios.create();

    axiosInstance.interceptors.response.use(
      (response) => {
        return response;
      },
      (error) => {
        console.error("Interceptor caught an error:", error);

        const message = error.response?.data?.message || error.message || "An unknown error occurred";
        const statusCode = error.response?.status || 500;

        const customError: HttpError = {
          ...error,
          message,
          statusCode,
        };

        return Promise.reject(customError);
      }
    );

    export { axiosInstance };

    // rest-data-provider/utils.ts
    import { HttpError } from "@refinedev/core";
    import axios from "axios";

    const axiosInstance = axios.create();

    axiosInstance.interceptors.response.use(
      (response) => {
        return response;
      },
      (error) => {
        console.error("Interceptor caught an error:", error);

        const message = error.response?.data?.message || error.message || "An unknown error occurred";
        const statusCode = error.response?.status || 500;

        const customError: HttpError = {
          ...error,
          message,
          statusCode,
        };

        return Promise.reject(customError);
      }
    );

    export { axiosInstance };

2. Import and Use axiosInstance in App.tsx:

    // App.tsx
    import { Refine } from "@refinedev/core";
    import { DataProvider } from "@refinedev/strapi-v4";
    import { axiosInstance } from "./rest-data-provider/utils"; // Correct import

    const App = () => {
      return (
        <Refine
          dataProvider={DataProvider(API_URL + `/api`, axiosInstance)}
          // other props
        />
      );
    };

    export default App;

    // App.tsx
    import { Refine } from "@refinedev/core";
    import { DataProvider } from "@refinedev/strapi-v4";
    import { axiosInstance } from "./rest-data-provider/utils"; // Correct import

    const App = () => {
      return (
        <Refine
          dataProvider={DataProvider(API_URL + `/api`, axiosInstance)}
          // other props
        />
      );
    };

    export default App;

By ensuring that you are using the axiosInstance from your rest-data-provider, you can make sure that the interceptor and error handling logic are correctly applied to all your API requests. For more details on setting up the notificationProvider and handling errors, you can refer to the Notification Provider documentation (https://refine.dev/docs/notification/notification-provider/) and the Handling Errors guide (https://refine.dev/docs/guides-concepts/data-fetching#handling-errors).
