Issues upgrading to Heroku 22 about heroku-buildpack-elixir HOT 4 OPEN

If someone is like me and wondering how to upgrade the buildpack to the latest version, just doing a

heroku buildpacks:set -a app https://github.com/HashNuke/heroku-buildpack-elixir.git

worked for me.

I also cleared the build cache on Heroku a couple of times which may or may not have helped. Instructions for this is available at Herokus help pages

from heroku-buildpack-elixir.

hi @abstractcoder,
Look at your provided logs, seems that your heroku-buildpack-elixir repo is not latest version.
Due to "Sorry,..." message was changed in commit a year ago.
Let pull the latest version of this repo and try again.
Other hand, please be careful about elixir+OTP version, I see that you try to use elixir v1.13.4 with Erlang 24.3.3.
They said Elixir v1.13.4 should use OTP 25 https://hexdocs.pm/elixir/compatibility-and-deprecations.html#compatibility-between-elixir-and-erlang-otp.
Thanks & br

I was running into this from a review app failure, and a heroku buildbacks:clear -a app also did the trick by bringing the installed buildpacks in line with what was defined in app.json.
