Heroku deploy help

[ryankauk]

This is just a general help question. I'm trying to deploy this onto heroku but am having now success. I'm pretty sure the app is running fine because I tested the same settings locally and it worked. However once I deploy it to heroku I get this:

2017-09-13T18:48:01.306884+00:00 heroku[worker.1]: State changed from starting to up
2017-09-13T18:48:04.125965+00:00 app[worker.1]: Logging to /app/mongo-connector.log.
2017-09-13T18:48:07.626384+00:00 heroku[worker.1]: State changed from up to crashed
2017-09-13T18:48:07.610283+00:00 heroku[worker.1]: Process exited with status 0

I'm not sure if it's the app related or heroku. I'm thinking I'm just missing a small configuration. I'm hoping someone could help me with this.
