What type is error for onError within AuthProvider?

I have an onError function in my custom authProvider.ts:
onError: async (error) => {
console.error("RECIEVED ERROR: ", error);
return { error };
},
onError: async (error) => {
console.error("RECIEVED ERROR: ", error);
return { error };
},
But I would like to give the error a type so i can use it to handle various situations, what is the type that is used for this error that invokes this onError function?

Hi @nick_montoya. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The onError function in your authProvider doesn't explicitly specify the type of the error parameter in the provided extracts. However, based on the usage and context provided in the extracts, it's likely that the error parameter is an object that contains at least a status property, which is used to handle different error status codes. For example, in one of the extracts, the onError function checks if the error.status is 401 or 403:
onError: async (error) => {
if (error.status === 401 || error.status === 403) {
return {
logout: true,
redirectTo: "/login",
error,
};
}

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

return {};
},
In another example, the onError function checks if the error.status is 418:
onError: (error) => {
const status = error.status;
if (status === 418) {
return {
logout: true,
redirectTo: "/login",
error: new Error(error),
};
}
return {};
},
onError: (error) => {
const status = error.status;
if (status === 418) {
return {
logout: true,
redirectTo: "/login",
error: new Error(error),
};
}
return {};
},
Based on these examples, you could define a type for the error parameter that includes a status property. However, without more specific information about the structure of the error object, it's difficult to provide a more precise type definition. For more information, you can refer to the refine documentation (https://refine.dev/docs/api-reference/core/providers/auth-provider/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Okay, so I have my onError function properly validating the access token to see if the user needs to login again, and the logic for returning the redirect for the login page works, but it never actually redirects me. I see in the console that it said it was going to redirect me, but it never does. This is my onError function code:
onError: async (error) => {
// if the error response contains an unauthorized message, then we need to verify that the users access token is still valid
// otherwise, we need to log the user out and redirect them to the login page so they can log back in and get a new access token
if (error.response.status === 401) {
const accessToken = localStorage.getItem("token");
if (!accessToken) {
return {
error: {
message: "Unauthorized",
name: "Token not found",
},
logout: true,
redirectTo: "/login",
};
}
const verifier = CognitoJwtVerifier.create({
userPoolId: config.cognito.USER_POOL_ID,
tokenUse: "access",
clientId: config.cognito.USER_POOL_CLIENT_ID,
});
try {
const payload = await verifier.verify(accessToken);
return { error };
} catch (error) {
console.log("returning redirect to login", error);
return {
error: {
message: "Unauthorized",
name: "Token not valid",
},
logout: true,
redirectTo: "/login",
};
} finally {
return { error };
}
}
return { error };
},
onError: async (error) => {
// if the error response contains an unauthorized message, then we need to verify that the users access token is still valid
// otherwise, we need to log the user out and redirect them to the login page so they can log back in and get a new access token
if (error.response.status === 401) {
const accessToken = localStorage.getItem("token");
if (!accessToken) {
return {
error: {
message: "Unauthorized",
name: "Token not found",
},
logout: true,
redirectTo: "/login",
};
}
const verifier = CognitoJwtVerifier.create({
userPoolId: config.cognito.USER_POOL_ID,
tokenUse: "access",
clientId: config.cognito.USER_POOL_CLIENT_ID,
});
try {
const payload = await verifier.verify(accessToken);
return { error };
} catch (error) {
console.log("returning redirect to login", error);
return {
error: {
message: "Unauthorized",
name: "Token not valid",
},
logout: true,
redirectTo: "/login",
};
} finally {
return { error };
}
}
return { error };
},

Let me check the knowledge base for you. One moment! :books: ---------------------- Based on the provided extracts, the onError function in your authProvider seems to be correctly set up to handle a 401 status error and return an object with logout: true and redirectTo: "/login" properties. This should trigger a logout and redirect to the login page. However, there are a few things you might want to check: 1. Ensure that the logout method in your authProvider is correctly implemented. The logout method is called when logout: true is returned from the onError method. Here is an example of a logout method implementation from the extracts:
logout: () => {
// ---
return {
success: true,
redirectTo: "/login",
};
},
logout: () => {
// ---
return {
success: true,
redirectTo: "/login",
};
},
2. Make sure that the useOnError hook is being used correctly in your application. The useOnError hook triggers the onError method when an error is thrown. Here is an example of how to use the useOnError hook from the extracts:
import { useOnError } from "@refinedev/core";

const { mutate: onError } = useOnError();

fetch("<http://example.com/payment">)
.then(() => console.log("Success"))
.catch((error) => onError(error));
import { useOnError } from "@refinedev/core";

const { mutate: onError } = useOnError();

fetch("<http://example.com/payment">)
.then(() => console.log("Success"))
.catch((error) => onError(error));
3. Check if the error object passed to the onError method contains the status property. The onError method checks the error.status or error.response.status to determine how to handle the error. If you've checked all of these and the issue persists, it might be a good idea to refer to the refine documentation (https://refine.dev/docs/api-reference/core/providers/auth-provider/) or seek help from the refine community. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Okay, so it seems that my logout function in my authProvider, is never getting called, this is the code for it:
logout: async () => {
console.log("CALLING LOGOUT");
await Auth.signOut();
return {
success: true,
redirectTo: "/login",
};
},
logout: async () => {
console.log("CALLING LOGOUT");
await Auth.signOut();
return {
success: true,
redirectTo: "/login",
};
},
Why would it not be getting triggered? how can I fix this?

Let me check the knowledge base for you. One moment! :books: ---------------------- The logout method in your authProvider should be called when logout: true is returned from the onError method. If it's not being called, there might be an issue with how the onError method is handling errors or how the useOnError hook is being used. Here are a few things you can check: 1. Ensure that the onError method is correctly returning logout: true when necessary. Based on your previous code snippet, it seems like it should be doing this when the error status is 401 and the access token is not valid. 2. Make sure that the useOnError hook is being used correctly in your application. This hook should be used to handle errors in your application and it triggers the onError method when an error is thrown. Here's an example from the extracts:

@kapa.ai Where do i place that code: const { mutate: onError } = useOnError(); Do I place that in my dataProvider if the error is happening when I try to perform CRUD operations? Or do I place that in my organization list page?
kapa.ai

Let me check the knowledge base for you. One moment! :books: ---------------------- The useOnError hook should be used in the component where you want to handle the error. This could be in your dataProvider if the error is happening when you try to perform CRUD operations, or it could be in your organization list page if that's where the error is occurring. Here's an example of how you might use it in a component:
import { useOnError } from "@refinedev/core";

function MyComponent() {
const { mutate: onError } = useOnError();

// ... your component logic

// Use onError in a .catch block or in a try/catch statement
fetch("<http://example.com/payment">)
.then(() => console.log("Success"))
.catch((error) => onError(error));

// ... return your component JSX
}
import { useOnError } from "@refinedev/core";

function MyComponent() {
const { mutate: onError } = useOnError();

// ... your component logic

// Use onError in a .catch block or in a try/catch statement
fetch("<http://example.com/payment">)
.then(() => console.log("Success"))
.catch((error) => onError(error));

// ... return your component JSX
}
In this example, if the fetch request fails and throws an error, the onError function from your authProvider will be called with the error object as a parameter. Remember, the useOnError hook is part of the refine library, which provides a set of hooks and components to help you build data-intensive applications.

@kapa.ai Okay, here is my dataProvider code, please tell where I should palce this, such that allow CRUD operations that result in an error, will use this onError logic to determine if the user should re-authenticate based on the status code:

Let me check the knowledge base for you. One moment! :books: ---------------------- In your dataProvider code, you're already using Axios interceptors to handle errors. You can modify the error interceptor to use the useOnError hook when an error occurs. However, hooks can't be used inside Axios interceptors directly because they're not React components or other hooks. A better approach would be to throw the error in the interceptor and then catch it in the component where you're performing the CRUD operations. In the catch block, you can then use the useOnError hook. Here's an example of how you might do this in a component:
import { useOnError } from "@refinedev/core";
import { dataProvider } from "./path-to-your-dataProvider";

function MyComponent() {
const { mutate: onError } = useOnError();

// ... your component logic

// Use onError in a .catch block or in a try/catch statement
dataProvider.getList({ resource: "myResource" })
.then((data) => console.log("Success", data))
.catch((error) => onError(error));

// ... return your component JSX
}
import { useOnError } from "@refinedev/core";
import { dataProvider } from "./path-to-your-dataProvider";

function MyComponent() {
const { mutate: onError } = useOnError();

// ... your component logic

// Use onError in a .catch block or in a try/catch statement
dataProvider.getList({ resource: "myResource" })
.then((data) => console.log("Success", data))
.catch((error) => onError(error));

// ... return your component JSX
}
In this example, if the getList method fails and throws an error, the onError function from your authProvider will be called with the error object as a parameter. Remember, the useOnError hook is part of the refine library, which provides a set of hooks and components to help you build data-intensive applications. For more information, you can refer to the refine documentation (https://refine.dev/docs/api-reference/core/hooks/authentication/useOnError/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Hey @nick_montoya, onError is called by refine when your data hooks has an error. If you set logout: true in the response, then we'll pass the redirectTo prop to the useLogout and it will handle the redirection if the logout function in your auth provider succeeds.
