Узел JS: SOAP для запроса веб-служб Java

Я пытаюсь вызвать службы Javaweb из модуля node js. Однако я получаю ошибку в библиотеке wsdl. Вот мой файл wsdl.

Вот мой test.js

  var soap = require('soap');
  var url = 'http://localhost:8888/webservice/helloworld?wsd';
  var args = {sayHello: 'ABC'};
  soap.createClient(url, function(err, client) {
      client.MyFunction(args, function(err, result) {
          console.info(result);
      });
  }); 

При запуске я получаю следующую ошибку -

node_modules/soap/lib/wsdl.js:68
  const [topLevelName] = nsName.split('|');
        ^

SyntaxError: Unexpected token [

$ node --version v4.2.6

Есть ли другой способ, как jquery, для вызова этой веб-службы Java?

node test.js 
/home/sjoshi/test.js:5
      client.sayHello(args, function(err, result) {
             ^

TypeError: Cannot read property 'sayHello' of undefined
