This error typically occurs in the context of SAP Gateway and OData services when there is a mismatch or an issue with the metadata or the service definition.

  Check Authorizations: Ensure that the user has the necessary authorizations to access the OData service and its metadata.
  Transport Consistency: If the service was transported, ensure that all related objects (like data elements, structures, etc.) are also transported and consistent in the target system.
