Heroku Error Loading Node Application with AWS-SDK

Question

My MEAN stack app is working perfectly locally but when I push it to Heroku where I'm hosting it I get "Application Error". This is the output I get when I do heroku logs --tail in my Terminal.

State changed from crashed to starting
Starting process with command `node app.js`
module.js:471
throw err;
^
Error: Cannot find module '../object/keys'

Typically you want to set up Heroku in the early stages of the app development to prevent any crazy errors. Your dependencies might be triggering this. I would try Digital Ocean as an alternative to Heroku.
