Hi. I received an inquiry from incubatorwiki that an error appears when setting preference.

[a943d740-7050-4878-86d8-72cde048f272] 2021-08-29 03:58:27: Fatal exception of type "MWException"

It seems to be related to this.

Just noticed one of these in 1.38.0-wmf.3.

Func edited projects, added MediaWiki-extensions-WikimediaIncubator; removed MediaWiki-Action-API.Feb 26 2022, 3:51 PM

Steps to reproduce:

Set incubatortestwiki-project to p via API
Go to https://incubator.wikimedia.org/wiki/Special:Preferences

Reason: API didn't validate values properly, incubatortestwiki-project set without a valid incubatortestwiki-code
