Heroku Rails setup ActionView::Template::Error ( isn't precompiled):
===

I am trying to setup my first Heroku hosted rails app and am running into what I believe is a precompile/pipeline issue.

I've followed all the appropriate steps:

    bundle exec rake assets:precompile    
    git add public/assets
    git commit -m "vendor compiled assets"git push heroku


But I am getting the following error:

    ActionView::Template::Error ( isn't precompiled):

Note there is a blank (" ") before "isn't precompiled" in the text of the error message - so it is not specifying the name of the missing precompiled file!

Has anyone run into this before?
