I cannot get NodeJS to work, at all. I’ve tried loading static resources, and also tried creating processes that served static resources. Neither works. The NodeJS service is running. I also get variations of this message:
Cannot GET /home
Any suggestions?
Several attempts later, it is mysteriously now working. 
And back to mysteriously not working. I’m on 2018.2, is NodeJS fully implemented??
I have a similar situation occurring. I noticed that the service will not start however so am assuming it has something to do with that. Sorry I know that’s not much help.
