$editCountByTaskType = array_fill_keys( array_keys( $this->configurationLoader->getTaskTypes() ), 0 ); should fill that array with an index for link-recommendation. The error happens a bit farther down:

@Dyolf77_WMF - just FYI there are issues with Suggested Editrs on arwiki currently. We are working on a fix ASAP.

Severe, none suggested edit task can be completed in arwiki.

That doesn't seem to be the case, from looking at Special:RecentChanges https://ar.wikipedia.org/wiki/%D8%AE%D8%A7%D8%B5:%D8%A3%D8%AD%D8%AF%D8%AB_%D8%A7%D9%84%D8%AA%D8%BA%D9%8A%D9%8A%D8%B1%D8%A7%D8%AA?hidebots=1&hidecategorization=1&hideWikibase=1&tagfilter=newcomer+task&limit=500&days=7&enhanced=1&urlversion=2

"PHP Notice" usually means that the PHP engine was able to ignore the error in some way; in case of undefined things, by using null instead (which due to PHP's type juggling is pretty much the same as 0, which would have been the correct value here). So I don't think there was any user impact.

PHP engine was able to ignore the error in some way

Apologies for the wrong assumption or wording, it's based on a local test. I think the edit saves may go through but the feedback on the save dialog was "Invalid response from server".

Ah, interesting. If you are still able to reproduce this, can you check the network logs and see what is in the VisualEditor API response?

FWIW what probably happened is that your development setup is configured to print errors, and the method was also invoked in a non-deferred way in some API, so the PHP notice was output in front of the JSON response and the browser could not parse it.
