coredns: V1.2.3 error in log: expected type *object.Service, but watch event object had type *v1.Service

With CoreDNS v1.2.3 and the Kubernetes plugin I see this error repeated in the logs: expected type *object.Service, but watch event object had type *v1.Service

Also I had a problem where a Kubernetes service resolved to the ip of the previous service (service was recreated). After I restarted the CoreDNS pods the service name resolved to the correct ip. I don’t know if this is related, I can open a separate issue for that if you want.
