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:
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!

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

@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

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.
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.
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.
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
.
By following these steps, you should be able to ensure

@kapa.ai I think its more the interceptor is not getting the error message form the responce data. It is getting the status code.
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:
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:
- 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:
This will help you understand the exact structure of the error response and adjust the interceptor accordingly.

@kapa.ai its like it does nto reach the error part of the interceptor
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:
Steps to Ensure Proper Error Handling:
1. Use the Axios Instance:
Ensure that all your API requests are using the axiosInstance
you exported.
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.

@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 };
},
};
