Slack Auth Redirect problem

I create a website with Lovable, deploy it to Supabase, then try to authenticate it with Slack. I’ve reviewed the config inside of Supabase and Slack and feel pretty confident that it’s set correctly. And still the authentication fails.

• Initial URL (Custom Domain): https://clicky-number-bloom.lovable.app/auth

• Redirect URL (Supabase Subdomain - Error Occurs Here): https://pnjlmmgjhoxxzclrgiew.supabase.co/auth/v1/authorize?provider=slack&redirect_to=https%3A%2F%2Fclicky-number-bloom.lovable.app%2Fauth%2Fv1%2Fcallback&scopes=identity.basic%2Cidentity.email

The log message from 2025-02-10T11:22:53.680000 was specifically crafted to contain a lot of details. But that also means I don’t want to share it here in public.

Can you review the situation from Lovable side? Is the proxy on Lovable or Supabase side, or both? Should I also send an email to Supabase support or will you do that?
