res.message || 'Error'

Error message

res.message || 'Error'

What it means

Generic error fallback shown in the axios response interceptor when the backend returns a custom business code other than 20000 and the response body carries no 'message' field; 'Error' is a sentinel placeholder for a missing server-side error description.

Solutions

1. Ensure the backend always returns a descriptive 'message' field alongside non-20000 business codes
2. Inspect the network response payload to identify the actual business error code and its cause
3. Handle specific business codes explicitly before falling back to the generic message
