• What is the cause and solution for SAP error message /UI2/CDMFCC_CHECK051 - Content is not json for (&1) &2 ?

  The SAP error message /UI2/CDMFCC_CHECK051 Content is not json for (&1) &2 typically indicates that the system is expecting a JSON response from a service or API call, but the content received is not in the expected JSON format. This can occur in various scenarios, such as when working with SAP Fiori applications or OData services.
  Causes:
  
  Incorrect Response Format: The service being called is returning data in a format other than JSON (e.g., XML, HTML, plain text).
  Service Errors: The backend service might be encountering an error and returning an error message or HTML page instead of JSON.
  Network Issues: There could be network-related issues causing the response to be malformed or incomplete.
  Configuration Issues: The OData service or the application might not be configured correctly to handle JSON responses.
  Authorization Issues: If the user does not have the necessary permissions, the service might return an error page instead of the expected JSON data.
  
  Solutions:
  
  Check the Service Response: Use tools like Postman or browser developer tools to inspect the actual response from the service. Ensure that it is returning valid JSON.
  Debug the Backend: If you have access to the backend, check the logs for any errors that might indicate why the service is not returning JSON.
  Review Service Configuration: Ensure that the OData service is correctly configured to return JSON. Check the service metadata and ensure that the correct content type is set.
  Check Network Connectivity: Ensure that there are no network issues affecting the service call. Test the service endpoint directly.
  Authorization Check: Verify that the user has the necessary authorizations to access the service. If not, adjust the roles and permissions accordingly.
  Error Handling: Implement error handling in the application to gracefully manage unexpected responses and provide meaningful feedback to users.
