[ERROR] Logstash: _dateparsefailure for xml output using the date plugin

The issue was resolved by using the force_array => true for the xml plugin. So my current filter looks like the below -

filter {

    mutate {
			convert => ["time", "integer"]
	}

    xml {
        source => "message"
        store_xml => false
        force_array => false
        target => "httpSample"
        xpath => [
			"/httpSample/@ts", "time",
			"/httpSample/@lb", "label",
            "/httpSample/@rc", "response_code",
            "/httpSample/@rm", "response_message",
            "/httpSample/responseHeader/text()", "response_header",
            "/httpSample/requestHeader/text()","request_header",
            "/httpSample/responseData/text()","response_data",
            "/httpSample/java.net.URL/text()","request_url",
            "/httpSample/method/text()","method"
        ]
    }
	

	date {
		match => ["time", "UNIX_MS"]
		target => "@timestamp"
	}
}
