Description

Hi there,
I followed through with the migration to V4 but am struggling to get the /auth/login page to render. It currently shows as a 404.

Reproduction

1. Removed the auth0 route.ts handle
2. Updated the .env attributes for v4
3. Added a middleware.ts file in the app folder.
4. Added the new lib/auth0.ts file
5. Updated the callbacks for my app
6. Removed the userprovider wrapper for my app and migrated everything over to session.user

All code was largely copy paste from the docs.
