node JS POST using soap in apigee

I am having some trouble in posting using node js in apigee.

the response I get is a blank []. Now if push the error, the error I get is [Error: connect EINVAL]

I guess it can't read the soap when I call it. I used this post as a reference, but it doesn't seem to work.

var http = require('http');
var request = require('request');
var async = require('async');
var querystring = require('querystring');


var body = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:over="http://oversea.interfaceBOSS.iptv.sample.com" xmlns:over1="http://oversea.common.iptv.sample.com" xmlns:bean="http://bean.oversea.interfaceBOSS.iptv.sample.com">'+
   '<soapenv:Header/>'+
   '<soapenv:Body>'+
