Connect REST does not map a property present in inheritance path



A REST connector was created using Create REST Integration wizard. The REST Service called by Pega has a property "description." The rule for this property is not created when Create REST Integration wizard was run because of the presence of an out-of-the-box Pega property Description in @baseclassWhen mapping Description property manually in the response data transform, the value is not populated. The service returns value for property "description."
