  Cause:

  Authorization Issues: The user may not have the necessary authorizations to access certain properties of the entity.

  Solution:
  
  
  Check the Data Model: Verify that the property mentioned in the error message exists in the entity type of the OData service. You can do this by checking the service definition in the SAP Gateway Service Builder (transaction code SEGW).
