Fix a Permission Denied Database Error

A structured diagnostic prompt that finds the real cause of an access error instead of widening your security.

When to use it

Debugging

Lovable Prompt

I am getting a permission error when [DESCRIBE THE ACTION]. The exact error text is:

[PASTE THE FULL ERROR]

Diagnose it in this order and tell me what you find at each step before changing anything:
1. Are the correct table privileges granted for the role making this request?
2. Does a policy exist for this exact operation on this table?
3. Can the policy condition ever be true for this user?
4. Is the request actually authenticated, and is the session reaching the server?

Then fix the real cause.

Do NOT make any policy permissive to make the error disappear, and do not disable row level security.

Why it works

Forcing a diagnosis before a change prevents the most common bad fix, which is widening the policy.
