I had the very same problem that you did. The issue lied in the fact that the bin folder was never pushed to the heroku repository.

I looked, I looked, and then I looked again, there was no rule in the .gitignore file for the bin/ folder...

Then, after a lot of pain and anguish, I realized that a couple of months before I had created a global .gitignore that would ignore all bin folders of all my repositories (why lord, why??).

I deleted the global .gitignore, and everything worked fine.
