XF 2.1 Alert job keeps requesting to be run

[Thriller Bark]

So earlier today one of my staffs sent and alert, and it gave the following error, but did send:

Error: Call to undefined method ErrorException::getRequest() in src/vendor/minishlink/web-push/src/WebPush.php at line 183

Now, this message pops up in the start page of the ACP:

There are manual rebuild jobs awaiting completion. Continue running them.

Clicking continue running them sends the alert again, then 5 minutes later it shows back up. I can't figure out how to remove the job manually, help?
