No Cedar supported app detected error in Sinatra Heroku app

Question

Seems like everything worked fine when I pushed to Heroku as shown below. Then I run into an error on the latter while following Heroku's Docs: http://devcenter.heroku.com/articles/ruby#install_the_heroku_commandline_client

With heroku.logs I get:

2012-01-11T06:36:43+00:00 heroku[slugc]: Slug compilation started
2012-01-11T06:36:43+00:00 heroku[slugc]: Slug compilation failed: no Cedar-supported app detected

2012-01-11T06:52:21+00:00 heroku[slugc]: Slug compilation started

How is there no Cedar-support detected when the Gemfile and Procfile are both in there? Also, nothing appears on the heroku webpage.

Works fine for me--double check your Procfile is up to date on Heroku. Here's the output of my push:

Counting objects: 46, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (28/28), done.
Writing objects: 100% (46/46), 15.23 MiB | 774 KiB/s, done.
Total 46 (delta 11), reused 46 (delta 11)

I cloned my app on Github, deleted my original Heroku app, and created a new one. Now I have it running! My conclusion is that the original Heroku app was created before I made all the new changes, and commits just weren't getting updated or pushed properly somehow. By creating a new app, I don't lose a thing since the code is the same, and Heroku allows for abundant app creations. I suspect this had something to do with git remote issues that I had not taken account for.
