This is not the same logic. Previously if the data product was missing we'd throw an exception at the
VertexHandle->orTrackHandle->call. Now you will put in an empty container. Please remove the check on return value ofgetByToken.There was a problem hiding this comment.

Ack. Good catch. Yes I'll make the change.
