invalid parameter target

[jaxxstorm]

I'm not sure if this is concat related or unbound related, but I haven't managed to figure it out.

I'm using the latest version of this module and the concat module. When applying the catalog I get the following error:

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Invalid parameter target on Concat_fragment[unbound-header]

I guess it's related to this:

concat::fragment { 'unbound-header':
    order   => '00',
    target  => $config_file,
    content => template('unbound/unbound.conf.erb'),
  }

But not exactly sure what the issue is?

Don't think this is unbound related, think it's concat related
