Internal error in ApiQueryAllUsers::execute: MediaWiki configuration error: The database contains more user groups than known to User::getAllGroups() function
Closed, ResolvedPublic

Description

The following query gives an error:
https://de.wikipedia.org/w/api.php?action=query&list=allusers&augroup=editor|autoreview&aulimit=1&auwitheditsonly=&aufrom=Halo1976

The original query used from client has limit=max, but the problem seems to be at this user, because it also fails for limit=1

The idea with prop=groups is good, when using that query [1] some groups are double listed (and consumed to many of the limit). Is that also fixed with the change or another bug?

The double listing is also fixed with the change. What's happening there is that it's listing each user's groups for as many times as the user matches augroup.

Note that auprop=groups often won't reach the limit, unless all the users have 0 or 1 non-automatic groups. This is intended behavior.
