Stuck on a 403 Forbidden error when the Data Action attempts to update a ServiceNow incident record via the standard REST API. The OAuth token is valid, verified via Postman, and the integration user has the correct roles and ACLs configured in ServiceNow. The Architect flow passes the correct headers, including Content-Type and Authorization, yet the response consistently returns a 403 with no helpful payload details. Any insights on potential header mismatches or ServiceNow-side restrictions that might be blocking this specific endpoint?
