This error typically occurs when the field you are trying to use as a source in a data operation (like a data transfer, mapping, or transformation) is not recognized as a valid or permitted source field in the context of the operation you are performing.
  Cause:
  
  Invalid Field Name: The field name specified may be incorrect or misspelled.

  Configuration Review: Check the configuration settings related to the data transfer or mapping process to see if there are any restrictions on the fields that can be used.
  Use Alternative Fields: If the field is not permitted, consider using an alternative field that serves the same purpose and is allowed in the operation.
