[XWjjbwpAMEkAABBJo88AAAAM] /wiki/Special:AbuseFilter/history/gibberish/item/5 ErrorException from line 47 of /srv/mediawiki/php-1.34.0-wmf.19/extensions/AbuseFilter/includes/Views/AbuseFilterViewEdit.php: PHP Notice: Cannot access property on non-object
We show filter 1 instead of a filter with ID = "gibberish", no other impact on the user. Definitely not blocking anything.
In the last 24 hours, 66 hits on wmf.19. No occurrencies for wmf.20, but that's just because no-one triggered it (I tried on a wmf.20 wikis and got the notice). Also, those URLs seem to be attempts of injection (?); at any rate, the nonsense and speed suggest non-human traffic.
Anyway, this creates annoying logspam, so I'm opening this task for reference even though I had already sent a patch a few days ago.
