Invoking RPC from RESTConf Fails after new data store changes

Invoking RPC from RESTConf was working fine with older data store, but with new data store changes, its failing.

Invoking RPC from consumer is working fine though. I tried to debug the issue, Controller throws an illegal state exception at uncheckedInvoke(final RpcService rpcService, final CompositeNode domInput) method inside BindingIndependentConnector.java at line 875. It tries to invoke mappingService.dataObjectFromDataDom(inputClass.get(), domInput), which calls RuntimeMappingModule.java's dataObjectFromDataDom method.

Above method calls YangTool's RunTimeGeneratedMappingServiceImpl.java class
