Need Help Integrating Auth0 with Existing Next.js Project on Vercel

[devops17]

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

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

3. 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 !!
