  Cause:
  
  Unsupported Data Type: The error indicates that the system encountered a data type that it does not recognize or support. This can happen if the data type is not defined correctly in the service or if there is a mismatch between the expected data type and the actual data type being sent in the request.
  Model Definition Issues: If the OData model is not properly defined or if there are inconsistencies in the metadata, it can lead to this error.

  Debugging: Use transaction code /IWFND/ERROR_LOG to check for any additional error messages or logs that might provide more context about the issue.
