Both personal and demo site showing application errors

I tried to deploy your app to my Heroku, but ran into application errors when navigating to my slug's site. I also noticed that when navigating to your public slug at "http://youtube-scrape.herokuapp.com", it is also showing an application error. Is this current build failing? I also attached logs from my instance to help with troubleshooting. I have tried adding the config variable per vic's suggestion here #15 (comment)

UPDATE: I went ahead and started troubleshooting your code and it seems to run fine on my PC. The issue looks to be, the Heroku slug's aren't executing npm install before npm start even when setting NPM_CONFIG_PRODUCTION=false. Let me know if you figure this out.

So far when I've seen this issue, setting that npm production config to false has solved it, so I'm not sure at this point what else could be happening.
My heroku site is failing because it used up all the free hours for this month.
