Check Home Assistant configuration add-on reporting unfamiliar errors

Prior to updating to 2021.12.10 I came across these errors which the Check Home Assistant configuration add-on produces, neatly following https://www.home-assistant.io/common-tasks/os/
Everything working just fine.
Configuration > Server Controls > Configuration check: Configuration valid!

Any direction where to look at would be really helpful. At this point I am clueless about this output.
