I'm using Heroku for the first time and am trying to launch a Rails 3.2.13 app, using Ruby 2.0.0 on a Cedar stack using PostgreSQL. My app runs fine locally, however I keep failing when pushing to Heroku. I've run this app on a dedicated server elsewhere, too, so I'm not sure why it's failing. I've also increased the log level to debug and this is still the only detail I receive.
