Unhandled rejection Error - horseman

Question

Im trying to run the example code from horsemanjs slightly modified:

var Horseman = require('node-horseman');
var horseman = new Horseman();
horseman
    .userAgent('Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0')
    .open('http://www.google.com')
    .type('input[name="q"]', 'github')
    .click('[name="btnK"]')
    .keyboardEvent('keypress', 16777221)
    .waitForSelector('div.g')
    .plainText()
    .log()
    .close();

It did work some days ago, but suddenly decided not to. I get this when I run it:

➜ Debug=horseman node test.js
   horseman using PhantomJS from phantomjs-prebuilt module +0ms
   horseman .setup() creating phantom instance 1 +3ms
   horseman phantom created +195ms
   horseman .close(). +13ms

With Bluebird debug:

➜  BettingSource DEBUG=horseman BLUEBIRD_DEBUG=1 node test.js

Phantomjs works from the terminal and I've tried to reinstall the node modules. I must note that have very little experience with node.

Note: To install phantomjs/horseman I did the following:

Downloaded the tar.gz file from phantomjs website and extracted it, placed it in bath /home/bin
Ran npm install phantom in /home/halvor/BettingSource
Ran npm install phantomjs
Ran npm install node-horseman

Both of the times I installed phantomjs it said phantomjs not found in path and downloaded it again.

Looks like the error came from an .htpasswd file in the same directory. Once I deleted it everything worked

You need to handle promise rejections with:

.catch(err => {
    // handle the error here
});

for every promise that is created in your program. Otherwise it will cash for any rejection in the promise chain.

See this answer for more details:

Should I refrain from handling Promise rejection asynchronously?
