  Check Data Mapping: Ensure that the data mapping aligns with the expected structure. If the source and target data structures have changed, update the mapping to reflect these changes.
  
  
  Test the Transformation: After making the necessary adjustments, test the transformation process again to ensure that the error is resolved.
