Could not autoload puppet/type/archive

[deric]

Output log

The error message is quite confusing, I had no idea what's going on.

 Could not autoload puppet/type/archive: Attempt to redefine entity 'http://puppet.com/2016.1/runtime/type/archive'. Set at unknown location on node ...

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 4.10.8
• Ruby: 2.3.3p222
• Distribution: Debian 9
• Module version: 1.3.0, 2.1.0

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

I've started seeing this error after making computing checksum optional:

if !empty($install_checksum) {
    Archive<| title == "${download_dir}/dcos_install.sh" |> {
      checksum      => $install_checksum['hash'],
      checksum_type => $install_checksum['type'],
    }
}

After removing this part of code everything works fine.
