puppet could not evaluate: could not retrieve information from environment

puppet can do exec on node, but cannot transfer file from module.

Ubuntu 14.04 server Puppet 3.8.4

Already tried:

• making file world readable
• disabling FW
• creating facter.d in module directory

On master:

/etc/puppet/puppet.conf

[main]
logdir=/var/log/puppet
vardir=/var/lib/puppet
ssldir=/var/lib/puppet/ssl
rundir=/var/run/puppet
modulepath = /etc/puppet/modules
factpath=$vardir/lib/facter

/etc/puppet/manifests/site.pp

node 'gitlab.domain' {
    include ssh
}

/etc/puppet/modules/ssh/manifests/init.pp

class ssh {
  exec { 'apt-update':
    command => 'apt-get update',
    path    => ['/usr/bin', '/bin', '/sbin'],
    logoutput => on_failure,
  }

  # ensure openssh installed
  package { 'openssh-server':
    ensure  => installed,
    require => Exec['apt-update'],
  }

  # make sure ssh keeps running
  service { 'ssh':
    ensure  => 'running',
    enable  => true,
    require => Package['openssh-server'],
  }


  # copy sshd_config
  file { '/etc/ssh/sshd_config':
    ensure  => 'present',
    notify  => Service['ssh'],
    source  => 'puppet:///modules/ssh/config/sshd_config',
    owner   => 'root',
    group   => 'root',
    mode    => '0600',
    require => Package['openssh-server'],
  }
}

On master:

ls -la /etc/puppet/modules/ssh/config

On node:

sudo puppet agent -t -v
