Hey fellow devs! I'm hitting a wall with an authentication sync issue between Clerk and Supabase in my React/TS app. Could use some expert eyes on this problem: The Issue: When users sign up or log in, I'm getting this error: Authentication error: Supabase connection failed: invalid input syntax for type uuid: "user_..." Sometimes followed by: Error creating/updating user: new row violates row-level security policy for table "users" My Setup: - React/TS app using Clerk for auth and Supabase (DB/Storage) - Deployed a Supabase Edge Function (sync-clerk-user) that receives Clerk webhooks when users are created/updated - Configured Clerk webhook endpoints to point to this function - Function is designed to use the Supabase service role key to upsert Clerk userIDs into the public.users table What I've Done: 1. Successfully deployed the Edge Function using supabase functions deploy sync-clerk-user --no-verify-jwt 2. Set up the webhook URL in Clerk's dashboard 3. Confirmed the function deployment shows success in terminal output 4. Started the local dev server and tested signup/login What's Puzzling Me: Despite having the webhook setup apparently correct, the app still throws the UUID error - suggesting that either: 1. The webhook isn't being received/processed correctly 2. The function has a runtime error I can't see 3. My client code might be trying to access Supabase resources before the sync completes Questions: - How can I effectively debug if the Clerk webhook is actually firing and reaching my function? - Where should I look in Supabase/Clerk to find detailed logs of the webhook attempts? - Any common gotchas with Clerk-Supabase user mapping that I might be missing? If anyone has experience with this Clerk+Supabase pattern or debugging webhook issues, I'd really appreciate the help!
