  Cause:
  This error typically occurs in the following scenarios:
  
  Duplicate Mappings: The same attribute is defined multiple times in the mapping configuration for the data source, leading to ambiguity in how the data should be processed.
  Incorrect Configuration: The configuration of the data source or the service might have been set up incorrectly, causing the same attribute to be referenced multiple times.
  Model Changes: If there have been recent changes to the data model or service definition, it might have inadvertently led to duplicate mappings.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Mapping Configuration:

  Review Data Model:
  
  Check the underlying data model to ensure that it aligns with the service definition. If there are changes in the data model, update the service accordingly.
  
  
  
  Regenerate the Service:
  
  After making changes to the mapping, regenerate the service to ensure that the changes take effect. You can do this by right-clicking on the service in the Service Builder and selecting "Generate".
