Error message

new Error(res.message || 'Error')

What it means

Rejection error created in the response interceptor after a non-20000 business code was already surfaced via Message; it propagates the server's 'message' (or the 'Error' sentinel when absent) to the caller's .catch so the promise chain does not silently treat the failed response as success.

Solutions

1. Catch the rejection in the calling code and handle the specific business error code
2. Have the backend return meaningful 'message' values so the propagated Error is informative
3. Centralize handling of auth codes (50008/50012/50014) to avoid duplicate handling at call sites
