Hey @pmiazga, please, can you have a look and do analysis? My guess is this is not impactful but it may be triggering some bad behavior with the implicit false returned. It would be good to know for triaging.

I mentioned this in chores last week. These errors relate to a botched deploy I did when fixing wikidata descriptions for wikidata and other wikis (
T188182). You can see in the error details it relates to mwdebug1002 so not production.
