Error 500 on Heroku (app Ruby on Rails)

Olive asked in Rails

Hello ,

I created an app on Ruby on Rails, and everything is ok on my localhost.

But on Heroku, it doesn't work :

We’re sorry, but something went wrong.
If you are the application owner check the logs for more information.

At the begining, I had a problem of database, who was not on PostgreSQL, but I fixed the problem.

When I check the logs, I can see the problem is coming from here :
