What it means

You tried to link a record to something that doesn't exist, like an order for a customer who isn't in the customers table yet.

How to fix it: paste this prompt into your AI builder

Fix prompt for Lovable, Bolt, Cursor, v0, Windsurf
Supabase returns a foreign key violation. Check the referenced column in the error: make sure the referenced row (e.g. the profile for this user) exists before inserting, and that the code sends the correct id (auth user id vs profile id). If profiles should exist for every user, add a trigger to create them on signup. Don't remove the foreign key or change unrelated code.

If the AI can't fix it: manual steps

  1. Check in the Table Editor that the referenced row actually exists.
