This error typically arises when the application is trying to access a field or property that has not been properly annotated in the metadata.
  Cause:
  The error occurs due to one of the following reasons:
  
  Missing Annotations: The required annotations for the specified field or entity are not defined in the OData service metadata.
  Incorrect Configuration: The configuration of the OData service or the UI5 application may not be set up correctly, leading to the inability to find the necessary annotations.
  Version Mismatch: There may be a mismatch between the version of the OData service and the expected annotations in the UI5 application.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check OData Service Metadata:
  
  Access the OData service metadata (usually available at the URL http://<host>:<port>/sap/opu/odata/sap/<service_name>/$metadata).
  Look for the entity or field mentioned in the error message and verify if the required annotations are present.
  
  
  
  Add Missing Annotations:
  
  If the annotations are missing, you will need to add them in the relevant CDS (Core Data Services) view or the OData service implementation.
  Use the appropriate annotation syntax to define the missing annotations.
  
  
  
  Update the OData Service:
  
  If you have made changes to the annotations, ensure that the OData service is reactivated or regenerated to reflect the changes.
  
  
  
  Check UI5 Application Configuration:
  
  Review the configuration of the UI5 application to ensure it is correctly set up to consume the OData service.
  Ensure that the correct service URL is being used and that the application is pointing to the right version of the service.
  
  
  
  Clear Cache:
