I'm not sure if #576 is a breaking change or not. it dropped some old code, but the OS were already missing in the metadata.json.

Nightly tests for Debian 12 fail
https://github.com/puppetlabs/puppetlabs-java/actions/runs/8273329382/job/22643950625
This happens due to the pinning of puppetlabs-puppet_agent to v4.13.0, which doesn't support Debian bookworm. Recently released v4.19.0 added support, using this version indeed fixes the nightlies.
It's questionable whether pinning should stay in place at all though - according to the commit messages there was a bit of a back and forth, initially the pinning was introduced because of instabilities in the modules when transitioning to Puppet 8 it seems.

[bastelfreak]

I still think the fixtures.yml should not pin any modules. It should pull the latest main/master branch so changes can be detected before they are released.

Alright, see #587
