Undefined method to_json

[AlexeyKupershtokh]

Hello. I've just installed the plugin and I see the following error message in the logstash log.

==> /var/log/logstash/logstash.log <==

{
  :timestamp=>"2015-04-17T04:56:17.436000+0300",

  ],

}

System is Ubuntu 12.04.3 LTS. Logstash 1.5.0RC2. The plugin was installed 30 minutes ago using bin/plugin install logstash-output-influxdb.

Logstash config:

output {
  if [type] == "gelf-ft-production-2.2" {
    influxdb {
      data_points => {
        'type' => 'type'
        'message' => 'message'
      }
      host => "localhost"
      user => "epic"
      password => "epic"
      db => "epic-forces-production"
    }
    if [level] <= 7 {
      elasticsearch {
        protocol => "http"
        host => "127.0.0.1"
        index => "ft-production-%{+YYYY.MM.dd}"
      }
    }
  }
}

Seems like a duplicate of #17.
