Heroku Symfony 3.2 Push rejected, failed to compile PHP app

Question

I'm having trouble while deploying my symfony web app on heroku, when previously it worked just fine. What could be wrong? This is the build log: http://pastebin.com/DXZH110S

Here is the relevant part of the log:

I would recommend pasting the relevant part of the build log here, and steps you've taken to resolve any errors that came up, otherwise there's not a lot to go on here. — Kateract

Finally I solved, the problem was the system variable SYMFONY_ENV=prod not set. https://devcenter.heroku.com/articles/getting-started-with-symfony#configuring-symfony-to-run-in-the-prod-environment
