Hello, we've been using this buildpack on Heroku-18, Erlang 22 and Elixir 1.10 just fine but we're now upgrading, and we get these errors:

Any idea on how to fix that? We've already tried purging the buildpack cache, no luck.

Thanks!

My fault, I had set the wrong elixir version to 1.12.0-otp-23 as that's what I use in asdf, but it's not a real Elixir version, this is working fine now:

erlang_version=23.3.4.1
elixir_version=1.12.0
always_rebuild=true
hook_pre_fetch_dependencies="./bin/predeps.sh"
