  Adjust the Query: If you are using a custom query, ensure that it is designed to return a single structure as the output. You may need to modify the query logic to ensure it adheres to this requirement.
  
  
  Regenerate the Service: If changes have been made to the structures or the service configuration, it may be necessary to regenerate the service to ensure that the changes are reflected correctly.
