Java 如何在node.js中使用SOAP成功请求adwords url？

Adwords API没有node.js的客户端库。如本文所述，您可以在其他语言中使用SOAP工具包。所以，我也这么做了。我用了如下方法

var soap = require('soap');
async function getLocation() {
let wsdlURL = 'https://adwords.google.com/api/adwords/cm/v201809/LocationCriterionService?wsdl';
const  url = 'https://adwords.google.com/api/adwords/cm/v201809';
let Id = "1000004";
let LocationName = "Quebec";
var args = { request: {
  "feilds":["Id", "LocationName", "CanonicalName", "DisplayType",
  "ParentLocations", "Reach"],
  "predicates":["LocationName","IN",LocationName]
  }
};

soap.createClientAsync(wsdlURL).then((client) => {
  console.log(client);                               //console 1
  console.log(client.getLocation(args));                 //console 2
  return client.getLocation(args);
}).then((result) => {
  console.log(result);                               //console 3
})
.catch((e)=> {
    console.log(e)
  });
}

对于控制台1，我得到

注意：XML脚本非常长。所以，我不能展示全部内容

对于控制台2，我得到： TypeError:client.getLocation不是函数

我试图将java示例转换为node.js。如何转换此示例
