Login Page Stuck After Successful Auth

When attempting to log in to my application, the login page remains stuck even though user information is correctly fetched and authentication appears successful. I’ve already added debug console logs and verified the authentication flow works perfectly in the Vercel preview deployment (v0.preview). However, in the production deployment, the user stays on the login page despite being authenticated. I’ve tried all recommended steps to resolve this (e.g., updating cookies, checking session context, verifying Supabase client/server setup), but nothing has resolved the issue. Please help troubleshoot this issue that only affects the production build.

Hey there, it would be very difficult to pinpoint the problem exactly without looking at your code. What do you mean by the user stays stuck on the login page? if by that you mean:

The cursor is spinning but nothing happens, it's usually a problem with the way you are handling the response, i'm leaning towards an error within the React useEffect hook.
Nothing happens, until you refresh the page which redirects you to the desired page, it's usually a problem within the navigation system after the authentification is complete.
Nothing happens, even when you refresh the page, it stays on the login page, it's probably an issue with the way you are handling your authentification.

I hope I can take a look at your code, and in doing that i might be of better help.
