• What is the cause and solution for SAP error message /UI2/CDMFCC003 - Invalid json ?

  The SAP error message /UI2/CDMFCC003 Invalid JSON typically indicates that there is an issue with the JSON data being processed in the SAP Fiori application. This error can occur in various scenarios, such as when the application is trying to consume a service that returns malformed JSON or when the application itself is sending invalid JSON data to the backend.
  Causes:
  
  Malformed JSON: The JSON data being sent or received is not properly formatted. This could be due to missing commas, brackets, or quotes.
  Data Type Mismatch: The data types in the JSON do not match the expected types defined in the OData service.

  Validate JSON: Use a JSON validator tool to check the structure of the JSON data being sent or received. Ensure that it adheres to the correct JSON format.

  Debugging: Use browser developer tools (F12) to inspect the network requests and responses. Check the payload being sent and the response received from the server.
  Error Handling: Implement error handling in your application to gracefully manage cases where the JSON is invalid or the service returns an error.
  Review Code: If you are developing or customizing the Fiori application, review the code that constructs the JSON payload to ensure it is correctly formatted.
