To fix the authentication bug, check if the JWT token expiration is properly validated in the middleware. Add a try-catch block around the token verification and ensure the refresh token logic handles edge cases when the access token expires during an active session.

The issue appears to be in your auth middleware. The JWT verification isn't handling token expiration correctly. I'd recommend: 1) Add proper error handling for expired tokens, 2) Implement token refresh logic before the token expires, 3) Clear invalid tokens from storage to prevent retry loops.

Your authentication middleware needs to handle JWT expiration. Wrap the token decode in try-catch, check the exp claim, and implement a token refresh mechanism. Also verify that your auth headers are being passed correctly in all API requests.
