This error typically arises when the system cannot find the necessary authorization checks for the object model representation that you are trying to access or use.
  Cause:
  
  Missing Authorization Object: The authorization object that is required for the operation is not defined or is missing in the system.
  Incorrect Configuration: The configuration for the object model representation may not be set up correctly, leading to the absence of the necessary authorization checks.
  Transport Issues: If the object model was transported from another system, the necessary authorizations may not have been transported correctly.

  Solution:
  
  Check Authorization Objects: Verify that the required authorization objects are defined in the system. You can do this by checking the relevant authorization roles assigned to the user.
  Review Configuration: Go through the configuration settings for the ESH object model representation to ensure that all necessary authorization checks are properly assigned.

  Debugging: If you have access to debugging tools, you can trace the authorization checks to identify where the failure occurs.
