Fix AuthApiError

✅ Solution

The "AuthApiError" in supabase-auth often arises from incorrect or missing configuration, particularly with environment variables or authentication providers. Double-check that your Supabase project URL and anon key are correctly set in your application and that any external authentication providers (like Google, phone auth) are properly configured and enabled in your Supabase project dashboard. Verify that your code handling authentication flows, especially `exchangeCodeForSession` or similar methods, correctly provides all required parameters like the auth code and code verifier (if applicable), ensuring they are non-empty.
