Heroku "Process exited with status 1" node.js app

I recently posted a question on a similar topic. I did a major overhaul of everything on the URL, and the same thing happened as last time: I could deploy everything and run it using heroku local web. When I went to the web dyno, it said I had an application error and I then check the logs. Here is what it said (I am using a project on github called atwork):

2017-05-02T01:16:25.212121+00:00 app[web.1]: npm ERR! You can get information on how to open an issue for this project with:

What I found weird was that there was no real explanation of the error. Here is the link to the project (I didn't change anything except for the mongodb connection URI). I can provide any other needed information.
