Railstutorial - App is working fine on local server but when I push to heroku I get application error

I'm doing the railstutorial by mike hartl and so far it's going well. How ever I'm stuck on lesson 7 conclusion.

I have basically got everything working, all rsync tests are passing and everything is working. I commit and push to GIT then push to heroko.

I use heroku open to open my app and the page that comes up gives me application error: An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details.

Here are my heroku logs:

Are you sure you have your factory_girl.rb in the helpers directory? Is your Gemfile up2date? It may be possible it's not tracked yet, thus your push ignored it.
