Issues upgrading to Heroku 22

[abstractcoder]

I'm trying to spin up a review app to test upgrading from Heroku 20 to the Heroku 22 stack.

I get the following error:

-----> Checking Erlang and Elixir versions
       Will use the following versions:
       * Stack heroku-22
       * Erlang 24.3.3
       * Elixir v1.13.4 
       Sorry, Erlang 24.3.3 isn't supported yet. For a list of supported versions, please see https://github.com/HashNuke/heroku-buildpack-elixir#version-support

When I follow the link it shows that Erlang 24.3.3 should be supported in Heroku 22 https://repo.hex.pm/builds/otp/ubuntu-22.04/builds.txt

Here is my full elixir_buildpack.config

# Elixir version
elixir_version=1.13.4

# Erlang version
# https://github.com/HashNuke/heroku-buildpack-elixir-otp-builds/blob/master/otp-versions
erlang_version=24.3.3

# Recompile Sentry to get latest source code
hook_pre_compile="mix sentry_recompile"

# Build Assets
hook_post_compile="mix assets.deploy"

EDIT: Switching from the release buildpack to the bleeding edge build pack resolved the issue. Is there any way for me to follow when Heroku 22 support is released?

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

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

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.
