Having troubles deploying to Heroku

[m1ket]

Hello,

I'm a bit of a newbie to NodeJS and AngularJS.

I have tried deploying your code to Heroku, but my app keeps crashing. I can't get it to start. Does this error message mean anything to you?

Hmmm, the error trace isn't very descriptive... The example app is also running on Heroku, so the first thing that comes to mind is that if you're using social logins maybe you didn't set the environment variables in Heroku yet? The expected environment variables can be found on the front page for this repo, while the Heroku documentation has a section on how to set these environment variables for your Heroku app. Let me know if you figure it out :)
