Error using https in filter section

[michaelv (Michael Leo Van Der Beek)]

Hi All,

I've gotten my logstash script working without https to port 9200.
However, I have turned on encryption but I cannot figure out why the filter section fails but the output section for the https works.

                # For updating of pool reference list
                mutate { add_field => { "ip_number" => "%{[IP_First_Integer]}" } }
                elasticsearch {
                        index => "singtel_dhcp_pool"
                        hosts => ["https://elk3:9200"]
                        user => "elastic"
                        password => "xxxxx"
                        ssl => true
                        ca_file => "/etc/logstash/ca.crt"

                        query_template => "/etc/logstash/conf.d/dhcp_pool_query.json"

                        fields => {
                                "Pool_Name" => "update"
                        }
                }
                mutate { remove_field => [ "ip_number" ] }

The error I am getting is.

                }
        }
}

Is it something wrong with the ssl section of the filter?
