R10K "does not return true" error for any git-sourced module in Puppetfile

[akomakom]

Describe the Bug

R10K documentation indicates that it is possible to specify git coordinates in the Puppetfile for each module. However, when attempting this, an error occurs and git checkout does not happen.

Expected Behavior

r10k should pull the requested git ref for the module

Steps to Reproduce

Steps to reproduce the behavior:

1. Install r10k as per documentation
2. Create a Puppetfile, eg:

# I know that this is redundant, but it also doesn't work with forks
mod 'puppetlabs-java',
    :git => 'https://github.com/puppetlabs/puppetlabs-java.git'
    :branch => 'main'

or

# Specifying a hash also does not work
mod 'puppetlabs-java',
    :git => 'https://github.com/puppetlabs/puppetlabs-java.git'
    :commit => '9255a978bc362f21654b9f9edd9d3d94002208f8'  # Also does not work

3. r10k puppetfile install
ERROR -> :branch: "main" === :branch does not return true
   or
   ERROR -> :commit: "9255a978bc362f21654b9f9edd9d3d94002208f8" === :commit does not return true

Environment

• r10k Version: tested with 5.0.0, 4.1.0 (installed at /opt/puppetlabs/puppet/bin)
• Platform: Redhat 9.4
• Puppet 8.10.0
