It sounds like you’re running into authentication issues when trying to connect integrations like Supabase and Stripe to your Vercel projects.

The popup is asking for your Supabase project URL and anon key. You can find these in your Supabase dashboard:

1. Go to your Supabase project dashboard
2. Navigate to Settings > API
3. Copy your Project URL and anon/public key
4. Paste these into the Vercel integration dialog

You can also check the following:

• Make sure you’re logged into the correct accounts for both services
• Try disconnecting and reconnecting the integrations
• Clear your browser cache and try again
• Ensure your projects exist in both Supabase/Stripe dashboards

Let us know how you get on!

@pawlean thanks for the reply.

Again, I have just created a new project and I have attached screenshots of exactly the issue I’m getting.

I did manually put in the project url and key as you explained, but nope, still forever going around in roundabouts. The first project I done was one-click, sorted. For reference, I have cleared cache, cookies, and have ensured that the Supabase i am using is linked to the vercel/v0 that I am using. I am just totally stumped. This has cost me lots of credits in debugging and forever going around in circles.

Now I am getting this when I build and try load the project.

I was enjoying vercel at first, now I am getting deeply frustrated. It spent almost 12 minutes telling itself that it fixed the issue, then it didn’t, it needed to make amends, then it fixed it, then it didn’t, it needed to make amends to the code again. This went on for literally about 12 minutes and it finally said it fixed it, did it? No.

I'm sorry for the delayed response, Robert. Appreciate you being patient with us! How'd you get on?
