Locked Task: Expert User Nudge

A notification of an error has popped up in my ACP, something that I have never seen before.

Apparently it has never run before, and nothing seems to appear in the logs.

Here is the error details:

TypeError: IPS\cloud\extensions\core\Notifications\Expert::parse_mobile_new_topics_to_review(): Argument #2 ($member) must be of type IPS\Member, array given, called in /var/www/html/5000051/system/Notification/Notification.php on line 881 (0)
