Error: { [Error: getaddrinfo ENOTFOUND] code: 'ENOTFOUND', errno: 'ENOTFOUND', syscall: 'getaddrinfo' } - node.js

Question

Fotolog is closing recently and I wanted to backup all of mine photos on there. Looking for something useful, I found this project: https://github.com/firstdoit/fotolog-backup
I installed npm and coffee with the instructions on the readme
but when I try to run:
coffee fotolog-build-index.coffee ticinowriting2
I receive this error:
doc#doc-mtn:~/fotolog-backup$ coffee fotolog-build-index.coffee ticinowriting2
{ [Error: getaddrinfo ENOTFOUND] code: 'ENOTFOUND', errno: 'ENOTFOUND', syscall: 'getaddrinfo' }
The code in "fotolog-build-index" is:
request = require 'request'
$ = require 'cheerio'
fs = require 'fs'
imageURLs = []
user = process.argv[2]
throw new Error("Usage: coffee fotolog-build-index.coffee <username>") unless user
buildIndexFromPage = (page) ->
request "http://www.fotolog.com.br/#{user}/mosaic/#{page}", (err, resp, html) ->
return console.error(err) if err
console.log "finished page #{page}... adding images"
images = $.load(html)("a.wall_img_container img")
images.map (i,img) ->
imageURLs.push $(img).attr("src").replace('_t','_f')
if images.length < 30
console.log imageURLs
console.log "got #{imageURLs.length} images"
fs.writeFileSync('index.json', JSON.stringify(imageURLs))
else
buildIndexFromPage(page + 30)
buildIndexFromPage(0)
Sorry for my bad english, im from switzerland and i know quite nothing about this kind of code

Answer 1

That error means the DNS resolver could not resolve the hostname (www.fotolog.com.br) to an IP address. I can verify this is indeed the case (dig gets NXDOMAIN). So unless you have the IP address there's not much you can do.
You could try just www.fotolog.com since that does seem to resolve yet, however the message on that site indicates data should have been downloaded before February 20, 2016.
