Can't Push Rails Project to Heroku

Question

So I've run into a little snag with a rails app that i'm trying to
deploy on to Heroku. When I attempt to push my app onto Heroku, I'm told
that rake tasks cannot be detected. In addition, I'm told that the
application file in the config folder cannot be loaded. I ran this little
command (bundle exec rake -P RAILS_ENV=production) to see if everything
in production mode checks out and I don't get any errors.

I really appreciate anyones help as this is my first time deploying an
app on Heroku. Thanks!
