I'm experiencing a 401 (Unauthorized) error when trying to fetch user data with a token in my React application using Axios. This happens when I attempt to call the getUserByToken function.
The authToken is set correctly in the Redux store, and I'm logging it right before the request. Here’s how I set the token: dispatch(auth.actions.login(token)); I'm using Axios interceptors to attach the token to the headers:

ps: the token is not present in the request headers in my browser’s developer tools (under the "Network" tab)
What could be causing the 401 (Unauthorized) error despite having the token set?
Are there any common issues with token handling in Axios that I should be aware of?
