PhantomJS - Upload file to facebook - facebook

Question

I'm trying to use PhantomJS 2.1.1 to update my profile picture on facebook. I'm able to log in, and navigate to the page where I should upload the picture, but page.uploadFile is just not working.
The last screenshot (page.render('end.png')) shows facebook alert "Please choose file to upload" confirming that page.uploadFile didn't work.
Any idea on how I can achieve this?
upload_page2.png
end.png
var args = require('system').args;
var page = require('webpage').create();
page.open('https://m.facebook.com', function(status){
if(status === "success"){
setTimeout(function(){
page.evaluate(function (args) {
document.getElementsByName("email")[0].value = args[1];
document.getElementsByName("pass")[0].value = args[2];
document.getElementById("loginbutton").click();
}, args);
}, 2000);
setTimeout(function(){
page.render('logged.png');
page.open('https://m.facebook.com/photos/upload/?profile_pic&upload_source=profile_pic_upload&profile_pic_source=tagged_photos_page', function(status){
});
}, 4000);
setTimeout(function(){
page.render('upload_page1.png');
page.uploadFile('input[name=file1]', 'http://proprofs-cdn.s3.amazonaws.com/images/games/user_images/misc/4288844624.png');
}, 6000);
setTimeout(function(){
page.render('upload_page2.png');
page.evaluate(function (args) {
var a = document.querySelectorAll('[type="submit"]');
a[0].click();
}, args);
}, 10000);
} else {
console.log("Error opening url \"" + page.reason_url + "\": " + page.reason);
}
setTimeout(function(){
page.render('end.png');
phantom.exit();
}, 15000);
});
