Node.js app crashes on deploying to Heroku

Question

I have a Node.js app which runs well locally, but when I deploy it on Heroku, it doesn't run.

I have deployed it from my Github repository.

Can some one try deploying the app from my repo and tell me what the cause of the problem is?

Try typing "heroku logs" on your terminal and share the logs here.

EDIT: It's "npm run start" or "node startfile.js" Ex: "node app.js" (can type only app without .js)
