I have an application I built that pushes images to Amazon S3 using Carrierwave. I forked and cloned that repo on Github. When trying to push it as a new application to Heroku, Heroku keeps throwing an error that it can't find my Amazon S3 secret key and ID and aborts the push. I have the original Secret Key and ID in my bash profile and pushing to heroku worked with that setup. I can't figure out why it isn't working with my clone of the application.
