Hi,
I am using NodeBB v1.16.2 and I am only using the default plugins alongside nodebb-plugin-user-invitations. If I don't have nodebb-plugin-user-invitations active users can successfully be redirected after the registration screen back to the home page while being automatically signed in after registration. If I have the plugin enabled, I run into a 502 Bad Gateway screen. The line which is causing the error is line 170 of lib/invitations.js. If I comment out that line the plugin works perfectly fine. The problem is, I don't know what I might be messing with if I remove the "checkConditionAndRewardUser" line from happening. Below is a full output of my log file and you can note that when line 170 fails it causes all of NodeBB to restart.
