This error indicates that there is a conflict due to a field name being repeated in the result set, which can happen in various scenarios, such as when multiple data sources or transformations are involved.
  Cause:
  
  
  Duplicate Field Names: The most common cause of this error is that the same field name is being used multiple times in the data extraction or transformation process. This can happen if:
  
  You are pulling data from multiple tables or sources that have fields with the same name.
  You have defined multiple transformations or calculations that result in the same field name being generated.
  
  
  
  Incorrect Mapping: If you are mapping fields from different sources and have not properly differentiated them, this can lead to conflicts.
  
  
  Data Model Issues: If the data model or structure has not been designed to handle unique field names, this can also lead to this error.
  
  
  Solution:
  
  
  Check Field Names: Review the data extraction or transformation logic to identify where the duplicate field names are being generated. Ensure that each field has a unique name in the result set.
  
  
  Rename Fields: If you find duplicate field names, consider renaming them in the transformation or extraction logic. You can use aliases or prefixes to differentiate between fields.
  
  
  Adjust Data Model: If the issue is related to the data model, you may need to adjust the model to ensure that field names are unique across different sources.
  
  
  Review Data Source Configuration: Check the configuration of the data sources to ensure that they are set up correctly and that there are no overlaps in field names.
  
  
  Testing: After making changes, test the extraction or transformation process again to ensure that the error is resolved.
