This helps you quickly understand what went wrong and how to fix it. **Error format** ```jsonon JSON theme={null} { "code": "", "title": "", "message": "" } ``` **Field definitions** * **`code`** – A stable, unique identifier for the error. Useful for programmatic handling and support requests. * **`title`** – A short, human-readable summary of the issue. * **`message`** – Detailed guidance to help you resolve the error. This structure ensures you always get actionable feedback when something doesn’t go as expected. ## Auth errors *** The following errors can occur when interacting with the [Auth APIs](/en/reference/access-manager/am-auth-apis) endpoints.
