Heroku node app crashing, can't figure out through errors

So I've been trying to find an answer on stack overflow for 2 hours now and I've found issues that are similar to mine but I can't seem to figure this out. I'm running node.js and my app on heroku is connected to my file. I can run it just fine using heroku local web but when I try to run heroku open it doesn't work. This is the only error I get back and it's no help..

2017-04-18T03:13:41.349539+00:00 app[web.1]: /app/node_modules/deasync/index.js:46 2017-04-18T03:13:41.349555+00:00 app[web.1]: throw err;

Any ideas how I should go about this? I have uninstalled my node_modules and reinstalled several times. I have tried numerous other ways of figuring this out but the answer is alluding me. Any help would be appreciated. Thank you
