Failed to perform CRUD operations from appgyver using SAP sample backend OData service.

Hi experts,

Recently I configured appgyver by consuming SAP sample backend service which is available in SAP BTP as odata integration. When we try to perform any crud operation from appgyver we are getting an error as shown below:

SAP BACKEND ODATA URL : https://mobile-service-cockpit-web.cfapps.eu10.hana.ondemand.com/cockpit/v1/org/810726b9trial/space/dev/app/com.sap.backend/service/sample-odata-v2-espm/v2

When we try to update while configuring the odata service we are getting an error as below:
Even if the status is mentioned as ok , but when check the response the value is getting updated to the desired one. It is displaying the original record.
