I’m having trouble deploying Phoenix 1.4 to Heroku. I’m not sure how to debug this issue. On my local machine everything is working fine, but I had Elixir 1.7.3 running on Heroku already. The only change I did was upgrade to Phoenix 1.4.
Here’s my buildpack:
erlang_version=21.0
elixir_version=1.7.3
always_rebuild=true
Here’s the log output.
