How can I omit empty objects from mapped JSON?

Hi all, I am trying to ensure that an object in my mapped JSON is omitted entirely from the result if its properties are all empty / skipped. In the screenshotted example, all of parcelCarrier’s properties resolve to empty or hit the skip condition. In this case I want the parcelCarrier: {} property to be omitted from the resulting JSON. Can anyone help me here? I have tried adding minProperties: 1 to the schema; same result.
