Heroku deployment error

Hello.I am trying to deploy a Node.js app but I get the following error after using git push heroku master on the terminal:

at=error code=H10 desc="App crashed" method=GET path="/" host=mmx3-weath

I have tried using heroku restart but it didn’t fix the problem.

This is my repo:

Mh…why you have two package.json? Have you tried to remove one?
By the way, i found a nice article about the H10 error from heroku:
