This error indicates that the system encountered a value that it could not convert due to a missing conversion rule or mapping for the specified field.
  Cause:
  
  Missing Conversion Logic: The error arises when the system tries to convert a value from one format to another (e.g., from a source system to a target system) but cannot find the necessary conversion logic for the specified field.
  Incorrect Data Format: The input value may not conform to the expected format or type, leading to conversion failures.
  Configuration Issues: There may be issues in the configuration of the data migration project, such as missing or incorrect mapping definitions.
  
  Solution:
  
  
  Check Mapping Configuration:

  Review Data Types:
  
  Ensure that the data types in the source and target systems are compatible. If there are discrepancies, you may need to adjust the data types or provide additional conversion logic.
