You turned on debug logging. If you do not you won't see it. It just
means that systemd tried to send a bus message to a bus connection
that already terminated. That's entirely OK though, and nothing to be
concerned about.

Really, ignore it. If you don't want to see it, don't turn on debug
logging...
