Have you considered switching to an EPP template? You can limit the data passed in to only valid types (otherwise catalog compilation failure), it's quite useful.
https://puppet.com/docs/puppet/5.5/lang_template_epp.html In the example below, you might do something like: $content = epp('modulename/template.epp', { 'dev' => $openvpnConf['dev'], }) file { '/path/to/file': content => $content, } With your template: ---------- <% | String $dev, | -%> ### <%= $dev %> ### ---------- If $dev inside the template ends up as anything but a string, splat goes your catalog with a helpful error message.
