Title: Message Title

Mohamed HADROUJ updated an issue   Hiera / HI-425 Hiera 3 + Puppet 4.2 can't manage empty value in yaml datasource Change By: Mohamed HADROUJ I'm facing some issues to use Hiera 3 with Puppet 4.2. When applying my puppet manifest using this command: {{puppet apply environments/production/manifests/init.pp --hiera_config=hiera.yaml}} I get the following error: {{Error: Evaluation Error: Error while evaluating a Function Call, Could not find data item myclass::ensure in any Hiera data file and no default supplied at /home/vagrant/temp/environments/production/manifests/init.pp:13:39 on node a}} Here is the directory structure : $ tree . ├── environments │   └── production │       ├── config.yaml │       └── manifests │           └── init.pp └── hiera.yaml content of config.yaml: {{ --- :backends:   - yaml :hierarchy:   - config }} :yaml:   :datadir: environments/production}} content of init.pp: {{ class myclass(   $version                          = $myclass::params::version,   $ensure                           = $myclass::params::ensure, ) inherits myclass::params {   notify {"$version": }   notify {"$ensure": } } class myclass::params {   $version                          = hiera('myclass::version', '1.0.0')   $ensure                           = hiera('myclass::ensure', 'running') } class {'myclass': } }} content of hiera data source: {{ --- myclass::version: '1.0.0' myclass::ensure: }} Looks like Hiera can't handle empty values from a yaml data source and/or replace them by default value?
