Using PhantomJS to embed all images of a webpage produces warnings but works

Question

I\'m trying to convert a webpage into a single file by embedding all the images (and other external resources once I passed this point). Here\'s how I run PhantomJs:

Answer 1

Those notices are printed when phantom.exit is called. They don't cause any trouble, but are not nice when you need a clean PhantomJS output. In your case you can suppress the notices by "asynchronizing" phantom.exit like this:

setTimeout(function(){
    phantom.exit();
}, 0);

I think the reason this is happening is because a large string is passed from the page context when phantom tries to exit.

I created a github issue for this.
