Code Details 401 Undocumented Error: Unauthorized

The 401 Unauthorized error is an HTTP status code that indicates the client making the request is not authorized to access the resource.

This error can occur in a variety of situations, including:

- The user is not logged in or has not provided valid authentication credentials.
- The user has logged in but does not have permission to access the requested resource.
- The user's session has expired, and they need to log in again.
- The authentication credentials are incorrect or have expired.
- The server has rejected the authentication credentials for some other reason.

To resolve this error, the client must provide valid authentication credentials or obtain the necessary permissions to access the requested resource. This may involve logging in again or contacting the system administrator to request access.
