Complete authentication failure due to permission denied errors on the auth.mfa_amr_claims table, preventing all user sign-ins and sign-ups.
All authentication attempts (sign-in and sign-up) are failing with a 500 Internal Server Error. The authentication endpoint /auth/v1/token?grant_type=password returns:
Technical Details:
Error occurs at the Supabase Auth API level - not client-side
HTTP 500 Internal Server Error from the auth endpoint
Root cause appears to be permission issues with the auth.mfa_amr_claims table
The table exists in the auth schema (verified in dashboard)
No MFA is configured - using standard email/password authentication only
Email confirmation is enabled only at registration
How can I solve this please ?
