Hi all, tried deploying my app on Gigalixir after updating my elixir_buildpack.config to the following:

elixir_version=1.12.1
erlang_version=24.0.1

The trace I’m seeing is

  error: failed to push some refs to 'https://git.gigalixir.com/<app_name_redacted>.git/'
Error: The process '/usr/bin/git' failed with exit code 1

Based on what I read online as possible reasons, the file https://s3.amazonaws.com/heroku-buildpack-elixir/erlang/cedar-14/OTP-24.0.1.tar.gz might not have been gzipped and may sport the .gz extension in error, but I’m not sure how to access it and verify this assumption.

Has anyone else seen this?

PS. I’m also using Github Actions and gigalixir-action for the deployment but I don’t think they’re related to this.
