  Adjust Model Configuration: If you are using a custom data model, ensure that it is correctly configured. You may need to adjust the model to use supported types.
  
  
  Regenerate the Service: After making changes to the data model or service definition, regenerate the service and re-activate it. This can often resolve issues related to metadata inconsistencies.
