Error ENOTFOUND on request to Google API Dialogflow with Nodejs

I have a Google Dialogflow application and when i do the the request to the api with a rest app (like insomnia o postman), it work. But, when i do with nodejs, it return a error: [The "(...)" added by me]

> getaddrinfo ENOTFOUND
> dialogflow.googleapis.com/v2/projects/(...):detectIntent
> dialogflow.googleapis.com/v2/projects/(...):detectIntent:80

This is my code on node:

var datajson = '{"queryInput":{"text":{"text": "hola", "languageCode": "es"}},"queryParams":{"timeZone":"America/Santiago"}}';

var options = {
  host: 'https://dialogflow.googleapis.com/v2/projects/si(...):detectIntent',
  method: 'POST',
  json: datajson,
  headers: {
    'Content-Type': 'application/json; charset=utf-8',
    'Authorization': 'Bearer ya29.c.El-3sdsa(...):detectIntent' 
  }
}

var req = http.request(options, function(res) {
  res.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
  });
}).on('error', function(e) {
  console.log("Got error: " + e.message);
});

In Insomnia:

Sometimes the ENOTFOUND error code is returned simply because there's no network connection, and so the API server cannot be reached.

Here is an example of the actual error message returned in such a case:

{
  message: request to https://www.googleapis.com/oauth2/v4/token failed, 
  reason: getaddrinfo ENOTFOUND www.googleapis.com
  type: system
  errno: ENOTFOUND
  code: ENOTFOUND
  config: {
    method: 'POST',
    url: 'https://www.googleapis.com/oauth2/v4/token',
    ...
  }
}

That error occurs because you're using an invalid value for host, which should be:

A domain name or IP address of the server to issue the request to. Default: 'localhost'`

And you should be using https instead of http package.

var options = {
  host: 'dialogflow.googleapis.com',
  path: '/v2/projects/si(...):detectIntent'
}

And there is no json option in https/http.request, you have to use req.write

req.write(jsondata);
req.end();

My recommendation is to use request or request-promise which will handle a lot of things for you.

const request = require('request');
const options = {
  url: 'https://dialogflow.googleapis.com/v2/projects/si(...):detectIntent',
  method: 'POST',
  body: datajson,
  headers: {
    'Content-Type': 'application/json; charset=utf-8',
    'Authorization': 'Bearer ya29.c.El-3sdsa(...):detectIntent' 
  }
}

request(options, (err, response, body) => {
    console.log(err, response.statusCode, body);
});
