[ghost]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 5.5.0
• Ruby: ruby 2.4.3p205 (2017-12-14 revision 61247) [x86_64-linux]
• Distribution: CentOS 7.4
• Module version: v6.4.0

How to reproduce (e.g Puppet code you use)

class { 'r10k':
    sources      => {
      'puppet' => {
        'remote'  => 'git@github.com:jas612/puppet.git',
        'basedir' => '/etc/puppetlabs/code/environments',
        'prefix'  => false,
      },
    },
    git_settings => {
      'provider'     => 'rugged',
      'repositories' => '
    - remote: "git@github.com:jas612/puppet.git"
      private_key: "/opt/puppetlabs/server/data/puppetserver/.ssh/id_rsa_puppet"
    - remote: "git@github.com:jas612/puppet-thecrimsontint.git"
      private_key: "/opt/puppetlabs/server/data/puppetserver/.ssh/id_rsa_thecrimsontint"',
    },
  }

What are you seeing

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Function Call, Failed to parse template r10k/r10k.yaml.erb:
  Filepath: /etc/puppetlabs/code/environments/production/modules/r10k/templates/r10k.yaml.erb
  Line: 3
  Detail: undefined method `to_h' for #<Array:0x7109a8b5>
 (file: /etc/puppetlabs/code/environments/production/modules/r10k/manifests/config.pp, line: 96, column: 16) on node puppet.mgmt.thecrimsontint.com

What behaviour did you expect instead

Properly render the template. v6.3.1 works just fine.

Hi @Jas612, thanks for the PR. Are you able to provide a patch for this or a test that verifies this broken behavior?

[ghost]

@bastelfreak it's in the "How to reproduce" section.

@Jas612 Can you provide the current contents of the r10k.yaml file that the previous version generates?

This looks to be duplicate #421
I get a similar issue after upgrading.

I am running a puppet 4 server. puppetserver version: 2.7.2
