Node.js &引用；GetAddrInfoReqWrap.onlookup[as oncomplete]（dns.js:76:26）“；

我正在尝试使用请求库运行lambda函数。我试图研究其他一些相同的问题，但找不到我真正需要的。以下是我的代码：

var req = require('request');

var headers = { 'X-AUTH-TOKEN': 'xxxx',
                'Content-Type': 'application/json',
                'Accept': 'application/json'};

var body = {"name" : "omkarEmailTest", "command_type":"SparkCommand", "language":"notebook", "note_id":"56563", "label":"YetAnotherSparkCluster"};

// Configure the request
var options = {
    url: 'http://api.quobole.com/api/v1.2/commands',
    method: 'POST',
    headers: headers,
    body: body,
    json: true
};

exports.handler = (event, context, callback) => {
 req(options, function (error, response, body) {
    console.log(body);
    callback(error);
 });
}

以下是我在aws lambda控制台中获得的日志：

Response:
{
  "errorMessage": "getaddrinfo ENOTFOUND api.quobole.com api.quobole.com:80",
  "errorType": "Error",
  "stackTrace": [
    "errnoException (dns.js:28:10)",
    "GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:76:26)"
  ]
}

Request ID:
"2295eee5-ec11-11e7-a9f4-dfa2f9f62b50"
