As a result, version metadata of DAGs that the requester is not authorized to access is returned.\n\n\nUsers are recommended to upgrade to Apache Airflow 3.1.8 or later, which resolves this issue."

Como resultado, se devuelven los metadatos de versión de los DAGs a los que el solicitante no está autorizado a acceder.\n\nSe recomienda a los usuarios actualizar a Apache Airflow 3.1.8 o posterior, lo que resuelve este problema."
