My build just failed on phoenix.digest vs phx.digest

[pbm]

I saw a change from a few minutes ago that hard coded phoenix_ex=phoenix

I am now getting the following doing a push:

 ** (Mix) The task "phoenix.digest" could not be found. Did you mean "phx.digest"?
remote:  !     Push rejected, failed to compile Phoenix app.

Same problem here. The offending line is to be found here: https://github.com/gjaldon/heroku-buildpack-phoenix-static/commit/fa862491d793c4ccb934caa04a8688b92fe0572e#diff-1d8aefca0d336c5e997af1fdf3402191R8

Workaround: Set phoenix_ex=phx explicitly in your phoenix_static_buildpack.config.
