I am trying to setup my Credential provider so that when the user fails to login (wrong username/password, for example) I can display the error message returned by the API in the client side.

I am trying to implement Auth.js in my Next.js project and I managed to make the login work but when I try to access the user data from the session the user object is always empty even tho the session says authenticated and has an expiration date.

When I am integrating next-auth functionality in my Next.js application, it throws an error: Catch-all must be the last part of the URL.
