I’m working on integrating Auth0 authentication into an existing Next.js project hosted on Vercel. Despite following the Auth0 Next.js SDK documentation, I’m encountering several issues during implementation.
Specific Challenges:

  1. Configuration Issues
    Getting 500 errors during authentication flow

Error: Missing required configuration: baseURL

  1. Redirect Problems
    Successful login doesn’t redirect properly to /dashboard
    Callback URLs seem mismatched despite correct settings

  2. Vercel-Specific Concerns
    How to properly set environment variables in Vercel
    Differences between local development and production configuration

What I’ve Tried:

  • Followed Auth0’s Next.js quickstart guide
  • Configured callback/logout URLs in Auth0 dashboard
  • Set up middleware and route handlers
  • Verified environment variables locally and in Vercel

ALSO I HAVE SET IT ON LOCAL
HERE I AM ABLE TO SIGN IN AND SIGN UP - But it doesnt redirect to required site gives error400 and error500 erros

I want help in sorting this out .
Even a Google meet will work !!
