  Cause:
  
  
  Missing Technical Definition: The error suggests that the system is unable to find the technical definition for a specific field or object that is required for the migration process. This could be due to:

  Configuration Issues: There may be configuration issues in the source or target system that prevent the migration tool from correctly interpreting the data.
  
  
  Data Model Changes: If there have been changes to the data model (e.g., fields added, removed, or renamed) in the target system, this could lead to missing definitions.
