iisnode HTTP Error 500.0

iisnode HTTP Error 500.0

I'm getting 500.00 error when trying to hit my server.js. I've looked
through all the related issues and tried suggested solutions, but I still
can't get this to work. I am looking for some help. It was working and
then it stopped. Could it possibly be a web.config issue?

There is an uncaughtException handler on my server.js and nothing is
coming up.

ETW trace:

Any help is greatly appreciated.
