  Cause:
  
  Missing Configuration: The member (field) referenced in the error message is not defined in the AIF configuration for the specified interface.
  Incorrect Mapping: There may be a mismatch between the raw structure and the configuration settings, leading to the system not recognizing the member.
  Changes in Structure: If there have been recent changes to the raw structure (e.g., fields added or removed), the AIF configuration may not have been updated accordingly.

  Review Recent Changes: 
  
  If there have been recent changes to the raw structure, review those changes and update the AIF configuration accordingly.
