Resources problem

[enves]

Hi,

I configure my manifest with this resource
nginx::resource::vhost { 'my.domain.com':
www_root => "/var/www/public",
location_cfg_append => { 'rewrite' => '^(.*) https://$server_name$request_uri? permanent' },
}

And when my puppet agent go to puppetmaster this error appear:

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: {"message":"Server Error: Evaluation Error: Error while evaluating a Resource Statement, Evaluation Error: Error while evaluating a Function Call, "" is not an Array. It looks to be a String at /etc/puppetlabs/code/environments/production/modules/nginx/manifests/resource/vhost.pp:349:3 at /etc/puppetlabs/code/environments/production/modules/profile/manifests/ciliaapp/nginx.pp:18

I really cant understand this error.

When I execute it in the local machine I recieve a lot o warnings like this

Warning: Unknown variable: '::nginx::config::root_group'
Warning: Unknown variable: '::nginx::config::conf_dir'.

I use puppet agent 4.6.0
