FirebaseError: Missing or insufficient permissions

What it means

Your Firebase database's security rules don't allow this read or write. Either the rules are too strict, the user isn't logged in yet, or the query asks for more than the rules allow.

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

Firestore returns "Missing or insufficient permissions". Show me the current firestore.rules, then write minimal secure rules for the collections the app uses (e.g. users can read/write documents where request.auth.uid matches the owner field). Make sure queries include where-filters that match the rules and only run after auth is ready. Do NOT set allow read, write: if true. Don't change unrelated code.

If the AI can't fix it: manual steps

1. Firebase console, Firestore, Rules: use the Rules Playground to test the exact request.
2. Remember to Publish rules after editing.
