NodeBB 3.3.8 Crashes on User Mention in Public Chat
Solved

So I want to start off with saying that notification on @mentions hasn't been working at all on our forum in public chat rooms. But it appears that the situation is now worse as specifically mentioning a user in public chat causes the forum to completely crash and reboot with the following error message:

I'm happy to do as much debugging as needed to get this fixed and provide whatever information is needed. Below is the list of plugins we're using.
