Mysterious Application Error on Heroku

I converted my app to rails 4. My test suite is green and it runs great
locally. I then deploy to Heroku and it crashed with no information at
all.
It just says “Application Error. An error occurred in the application
and your page could not be served”

Heroku logs don’t give any info either:

Also the console doesn’t run, i get the same error

In my misery I ran pg:reset and rake db:migrate. Those were the only two
commands that did run ok, but the app is still crashing in production
only.

Anyone has any ideas?

Thanks.

Send a proper trace from development environment, if it won’t boot up
then the problem is either in a gem, gemfile or config/*
