Symfony deployment on Heroku

  deployment, github, heroku, symfony

I really need your help with a Symfony deployment that I try on Heroku.
I connect everything to my Github repo and it works well but I didn’t have any database connection. I setup all my Symfony to PostgresSQL and in doc it says that Heroku manage on his own all the connection. Effectively when I write :

heroku config

I have the DATABASE_URL with what seem like a good url. But in fact I don’t have nothing online just a 404 error. My application works very well in local and all the CI/deployment to Heroku works the same.
If you have any idea thank you 🙂
