All of the json files (client, api, etc.) in /etc/sensu/conf.d remain empty

[nagyt234]

Description of problem

• What did you do?
  I've tried to install sensu using the puppet module:

puppet install sensu/sensu

• What happened?
  RabbitMQ and Redis are installed. Sensu is installed after I installed the APT key manually (see issue Sensu packages cannot be authenticated #654) but sensu client is not started because of a ruby error (s. below), which I guess caused by the empy /etc/sensu/conf.d/client.json file. As all other files, redis.json, rabbitmq.json and api json are empty, too.
• What did you expect to happen?
  That sensu-client and sensu-api are also started and the configuration files are fileld up according to the initialization parameters of the class sensu.
• How can someone reproduce the problem?
  Use the manifest file below.

Command used and debugging output

• What does your puppet config look like (including any hiera config)
  This is the manifest file in my modul "sensu_server":

            $rabbitmqctl_path = "/usr/sbin:/usr/bin:/bin"
          }
         default: { fail("puppet_agent: unsupported Ubuntu release: ${operatingsystemrelease}") }
       }
    }

The fragment of output of the command on the client: puppet agent --onetime --no-daemonize --verbose:

• Is this a masterless or master based puppet setup?
  It's a master base setup.

Platform and version information

• Your OS: Ubuntu 16.04 on the puppet client, 12.04 on the puppet server
• Your Ruby version: 2.3.1p112 on the puppet client, 1.9.3p484 on the puppet server
• Your version of Puppet: opens source 3.8.5 on the puppet client, 3.7.3 on the puppet server
• Your version of Sensu: not so far, the package is not installed by this module
• Your version of this module: 2.2.0

Anything else to add that you think will be helpful?

The problem was caused by the pluginsync settings on the puppet agent. It has to be enabled, see puppet documentation. The weird thing is that no error message appears anywhere about missing (custom) types.
