This answer seems to have been answered in various ways, but none that seemed to fit my exact issue. I am using the app from RailsApps https://github.com/RailsApps/rails-devise-pundit
The app works perfectly on my local Ubuntu 14.04 machine, but when I deploy it to Heroku, I get an 'application error' on the page my app should have been started. I ran 'heroku logs' but can't be sure what the exact issue is. Below is my log as well as my Gem file. Any help would be greatly appreciated. Thank you.
Here is My Log
