Can't catch an error thrown when there's an invalid status code 522

Hi,

I'm trying to scrape the url below but after some time it shows an error: http://www.lazygamer.net/boost/the-top-10-gaming-youtubers-in-2014-so-far/

assert.js:86
  throw new assert.AssertionError({
        ^

I also attached a screenshot of the webpage loaded from the browser if it's helpful.
