  Cause:
  This error usually indicates that there is a conflict between the old and new values during a data transformation or mapping process. Specifically, it suggests that the system is trying to assign a new value to a field, but the old value is still being referenced or is not being updated correctly. This can happen due to:
  
  Data Inconsistency: The old value is still present in the source data, leading to a conflict when trying to assign a new value.
  Mapping Issues: There may be an issue in the mapping configuration where the old value is not being correctly replaced or updated.
  Transformation Logic: The transformation logic may not be correctly defined, causing the system to revert to the old value instead of applying the new one.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Consistency: Ensure that the source data does not contain any references to the old value. You may need to clean or update the source data before the transformation process.
