What it means

The key your app uses to talk to Supabase is wrong, belongs to a different project, or is missing. Often keys were copied from an old project or rotated.

Fix prompt for Lovable, Bolt, Cursor, Replit, v0, Windsurf
Supabase says "Invalid API key". Check that the Supabase URL and anon/publishable key come from the SAME project, are read from env vars with the right names, and contain no extra spaces or quotes. Make sure the browser uses only the anon/publishable key and server code uses the service key from a server-only env var. Don't change anything else.

If the AI can't fix it: manual steps

  1. Copy fresh values from Supabase Project Settings, API; update them on your host, and redeploy.
