Stubby error in the system log

Hi Anyone can advise on this? I have no idea what's wrong...

Wed Oct 26 17:00:33 2022 daemon.err stubby[10417]: Could not get qname from query: A helper function for dicts had a name argument that for a name that is not in the dict.

It doesn't look like a stubby problem. Stubby is complaining about the content of the query, specifically for the qname. Maybe it is malformed. Does it happen often? If yes, then it might be worthy to troubleshoot it with a packet capture.

I noticed it today, I don't check the system log often, so I can't be sure of that
