Errors people hit

What you seeFix
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.
declined Content declined by a guardrail
A value is outside what the template allows: an off-palette color, a size out of range, locked text.
Keep the value within the guardrail or make no change. Guardrails are enforced by Stensul and cannot be overridden from a chat.
