  Cause:
  The error message /UI2/CDMFCC_CHECK054 Json of (&1) &2 lacks member &3 can occur due to several reasons:

  Version Mismatch: There may be a mismatch between the frontend application and the backend service version, leading to discrepancies in expected fields.

  Update Frontend Application: If there have been changes in the backend data model, ensure that the frontend application is updated to reflect these changes. This may involve updating the UI5 application or the Fiori elements.
  
  
  Debugging: Use debugging tools to trace the execution and identify where the JSON response is being generated and why the member is missing.
