The "bh" language code was removed (T91240: "bh" is not a valid language code) and bhwiki uses "bho" but sitematrix incorrectly believes the wiki is in "bh" language. There is no name for the incorrect code.

Where does sitematrix fetch the incorrect code from?

On the cluster, it appears it gets the list of codes from the file langlist in the operations/mediawiki-config repo. But since the wiki itself is still "bh.wikipedia.org" with database name "bhwiki", I'd be wary that simply changing that would break something.

IMO https://gerrit.wikimedia.org/r/193802 should be reverted. Names.php contains a bunch of "invalid"/"wrong" language codes (e.g. als, be-x-old) that are needed for backward compatibility and also to make the WMF cluster work in its current configuration.

Whether this fixes the problem or not, I can't say, but it should still happen regardless. A proper solution to the mess of legacy language codes needs to be figured out, not just a piecemeal approach that breaks various things along the way.

There is a short discussion on the problem here too https://en.wikipedia.org/wiki/Wikipedia_talk:AutoWikiBrowser/Bugs#TypeInitializationException_Unable_to_log_in

I have uploaded an AWB snapshot release to https://sourceforge.net/projects/autowikibrowser/files/autowikibrowser/Snapshots/ named 5.5.6.0-S, this is the 5.5.6.0 release with a workaround for the Bihari wiki not having a name.

Well, I was doing the same in parallel... :)

"A bunch" is an exaggeration. Most of the incorrect language codes are valid under at least one standard and/or are not used as a wiki's language code. "bh" is a unique case of egregious typo.

I am temp admin on bhwiki. I list here some old discussions (I never participated, I am still not much technical to understand these things):

Is the priority of this task still correct or should it be lowered?
This task has been "Unbreak now" priority but no activity for nearly one month.
https://gerrit.wikimedia.org/r/#/c/211906/ was reverted in https://gerrit.wikimedia.org/r/#/c/211906/

(And Nemo_bis' patch in https://gerrit.wikimedia.org/r/#/c/211119/ for SiteMatrix is still awaiting review.)

Anything happening regarding this task??

Somebody needs to review Nemo_bis' patch in https://gerrit.wikimedia.org/r/#/c/211119/ for SiteMatrix .
CC'ed as reviewers in Gerrit are @Anomie and @Nikerabbit - is that correct or are there better candidates?

Has this been fixed? https://en.wikipedia.org/w/api.php?action=sitematrix shows a name after the "code": "bh"
