создать контакт из node.js для mautic uisng Mautic rest api

Question

Я использую модуль npm mautic-node для связи с mautic REST API из node.js.Моя цель - создать контакт из моего приложения в mautic dashboard с помощью mautic REST API, но я сталкиваюсь с проблемой при создании контакта из узла. js.Пожалуйста, помогите мне разобраться в этом.

var mautic = require('mautic-api-node');
var request = require('request');
var config = require('../config/config.js');
var request = require('request');
exports.saveContact = (req, res) => {
queryParameters = JSON.stringify(req.body);
var username = "mauticUsername";
var password = "mauticPassword";
var auth = "Basic " + new Buffer.from(username + ":" + 
password).toString("base64");


var options = {
   url: 'https://mautic-url/api/contacts/new',
   method: "POST",
   form: queryParameters,
   headers: {
       "Authorization": auth
   }
};
request(options, (error, response, body) => {
   if (error) console.log(error);
   console.log("Body", body);
})

}

Я передаю это тело запроса бэкэнду: -

  {
  "firstname":"firstname",
  "ipAddress":"Ipaddress",
  "lastname":"lastname",
  "email":"email"
  }

когда я запускаю этот код, я получаю этот ответ
