Thanks for the additional info!

So, the issue here is that the title of a resource is expected to be a string or an array of strings. Overloading the title by passing in a hash of data, instead of adding parameters to a type, is not guaranteed to work and future versions of the Puppet language may throw an error for this case.

Your link defined type should declare parameters for src and dst instead of picking them out of name:

  define link (

    $src,

    $dst,

) {

    exec { "mkdir -p ${dst}":

      unless => "[ -d ${dst} ] || [ -L ${dst} ]",

      path => [ "/bin", "/usr/bin" ]

    file { $dst:

      ensure => link,

      target => $src,

      require => EXEC["mkdir -p ${dst}"],

      force => true

The case of creating many resources from a collection of data, can be approached using the create_resources function. This function takes a hash of 'title_string' => parameter_hash values and creates a new resource of a given type for each entry. To use this function, the links entry in your Hiera data would change from an array of hashes to a hash of hashes:

  links:

     some_titlestring_for_link_1:

       src: /nas/glustertest

       dst: /tmp/glustertest

     some_titlestring_for_link_2:

       src: /nas/cifstest

       dst: /tmp/test3/cifstest

Then, instead of declaring {{link

{ $links: }

}}, you can use create_resources:

create_resources(link, $links)

Hopefully that info helps, I'm going to close this issue out as a duplicate of PUP-2935 which contains some more details about the underlying problem.

PUP-3530

I'm trying to pass a simple array to a custom define and fails with error:

{code}
err: Could not retrieve catalog from remote server: Could not intern from pson: Could not convert from pson: Could not find relationship source "Foo::Map[idbazip2.2.2.2]"
{code}

I think that code is very correct:

{code}
$foo = [{"id" => "bar", "ip" => "1.1.1.1"},...
