Firebase Cloud Functions bitly example throwing error

Question

I'm following the example from the github repository to short a link url

https://github.com/firebase/functions-samples/tree/Node-8/url-shortener

The error is giving is the following

12:49:56.472 a. m. shortenUrl Function execution took 509 ms, finished with status: 'error' 12:49:56.464 a. m. shortenUrl RequestError: Error: getaddrinfo EAI_AGAIN api-ssl.bitly.com:443 at new RequestError (/srv/node_modules/request-promise-core/lib/errors.js:14:15) at Request.plumbing.callback (/srv/node_modules/request-promise-core/lib/plumbing.js:87:29) at Request.RP$callback [as _callback] (/srv/node_modules/request-promise-core/lib/plumbing.js:46:31) at self.callback (/srv/node_modules/request/request.js:185:22) at emitOne (events.js:116:13) at Request.emit (events.js:211:7) at Request.onRequestError (/srv/node_modules/request/request.js:881:8) at emitOne (events.js:116:13) at ClientRequest.emit (events.js:211:7) at TLSSocket.socketErrorListener (_http_client.js:387:9) at emitOne (events.js:116:13) at TLSSocket.emit (events.js:211:7) at emitErrorNT (internal/streams/destroy.js:64:8) at _combinedTickCallback (internal/process/next_tick.js:138:11) at process._tickDomainCallback (internal/process/next_tick.js:218:9)

I'm really new at functions but I did follow all the steps from the documentation there.

here is my index.js inside my functions folder

const functions = require('firebase-functions');
const BitlyClient = require('bitly');
// TODO: Make sure to set the bitly.access_token cloud functions config using the CLI.
const bitly = BitlyClient(functions.config().bitly.access_token);

// Shorten URL written to /links/{linkID}.
exports.shortenUrl = functions.database.ref('/links/{linkID}').onCreate(async (snap) => {
  const originalUrl = snap.val();
  const response = await bitly.shorten(originalUrl);
  return snap.ref.set({
    original: originalUrl,
    short: response.data.url,
  })
});

and my package.json in order to compile the the neccesary for bitly

{
  "name": "url-shortener-functions",
  "description": "URL Shortener Firebase Functions sample",
  "dependencies": {
    "bitly": "^5.1.7",
    "firebase-admin": "~6.0.0",
    "firebase-functions": "^2.0.5"
  },
  "devDependencies": {
    "eslint": "^4.13.1",
    "eslint-plugin-promise": "^3.6.0"
  },
  "scripts": {
    "lint": "./node_modules/.bin/eslint --max-warnings=0 .",
    "serve": "firebase serve --only functions",
    "shell": "firebase experimental:functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "engines": {
    "node": "8"
  },
  "private": true
}

I also did npm -install bitly inside my functions folder but still throwing that error

Also I added my link inside my database as the documentation states

/functions-project-12345
    /links
        link-123456: "https://my.super.long-link.com/api/user/profile/-jEHitne10395-k3593085"

Any clue ? thanks

it complains, that it cannot resolve for the remote host:

RequestError: Error: getaddrinfo EAI_AGAIN api-ssl.bitly.com:443

therefore I'd assume, that a paid plan is required, in order to perform this external API call.
