  Solution:
  
  Check Entity Set Configuration: Review the entity set configuration in your OData service. Ensure that each navigation property is only bound once to the entity set.
  Review Associations: Check the associations defined in your data model. Make sure that each navigation property is correctly defined and that there are no duplicate associations pointing to the same navigation property.
  Modify the OData Model: If you find that a navigation property is indeed being used multiple times, you will need to modify the OData model to ensure that each navigation property is unique within the context of the entity set.
  Regenerate the Service: After making changes to the model, regenerate the OData service to ensure that the changes take effect.
  Test the Service: After making the necessary adjustments, test the OData service to confirm that the error has been resolved.
