onError

public void onError(io.grpc.Status error)

Description copied from interface: XdsClient.ResourceWatcher

If the code needs to be propagated to the channel, override it with Status.Code.UNAVAILABLE. - Keep Status description in one form or another, as it contains valuable debugging information.
