Almost there: a few settings need attention in Vercel.
Check these:
- NEXT_PUBLIC_SUPABASE_URL should look like https://yourproject.supabase.co (no extra path or spaces)
- NEXT_PUBLIC_SUPABASE_ANON_KEY contains a space or line break; paste it again
- SUPABASE_SERVICE_ROLE_KEY contains a space or line break; paste it again
After fixing them, redeploy so the new settings take effect.
