CopyPatrol is currently returning a generic message with a 500 status code: "A website error has occurred. The website administrator has been notified of the issue. Sorry for the temporary inconvenience." This also occurs when run on a local server.
The underlying stacktrace is as follows:
ErrorException: Trying to access array offset on value of type bool in /app/src/Controllers/CopyPatrol.php:200

This line mentions ORES, which is currently in the process of being decommissioned and replaced with LiftWing. The outage which began at 2023-09-25 09:14:53 UTC coincides with https://gerrit.wikimedia.org/r/c/operations/puppet/+/959762/, which seems to have switched https://ores.wikimedia.org to a backend without the /v2/ endpoints that CopyPatrol relies on (at CopyPatrol.php#L63).
