When we update a BgpAsAService object from ui, it is updating all fields including bgp-router-refs. Also, it sends vmi refs to empty first, then sets it to the old value again later. This interferes with schema transformer updating bgp-router-refs. Please see the logs below that were seen when we created the object with a vmi, then added an ip address:
