I find the existing documentation in the net very confusing so I havent' used epp yet. E.g. according to https://puppet.com/docs/puppet/5.4/lang_template_epp.html this should work: content => epp("openvpn/etc/openvpn/config.epp", { openvpnConf => $openvpnConf, openvpnMode => $openvpnMode, instance => $instance }), <%- | Hash $openvpnConf, String $openvpnMode, String $category, String $parameters, String $instance | -%> <% ({ 'Misc' => [ 'script-security', 'plugin', 'up', 'down', ], }).each |$category, $parameters| { -%> <%= $category %> <% } -%> Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Function Call, epp(): Invalid EPP: Ambiguous EPP parameter expression. Probably missing '<%-' before parameters to remove leading whitespace at /etc/puppetlabs/code/modules/openvpn/templates/etc/openvpn/config.epp:6: 6 at /etc/puppetlabs/code/modules/openvpn/manifests/init.pp:28:22 on node h2786452.stratoserver.net The same documentation uses different sysntax, once without '$' $servers.each |server| and then with '$' $ntp::restrict.flatten.each |$restrict| What is correct? And what is wrong with the code above? Do I need to declare only variables that I pass to the epp or also those I create within the epp? -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
