Errors people hit

What you see	Fix
401 Authentication expired or missing The session's authorization expired.	Sign in again when the host prompts. On a 401 or 403, the server's instructions tell the model to re-check sign-in first.
403 Insufficient OAuth scope (403): The token lacks the required scope The API connection doesn't have the scope this tool needs.	An admin adds the scope to the API connection. Then sign in again: adding a scope revokes existing tokens.
403 API error (403): Action is unauthorized. The signed-in user's role lacks the permission, for example `edit_campaign`.	Grant the permission to the user's role in Admin > Users & Roles. It works for other users on the same connection.
