CasperJS and 'Unsafe JavaScript attempt to access frame with URL' error

Question

I have simple page with javascript which validates email written in input:

email.html:

<!DOCTYPE html>
<html>
    <head>
        <title>Email validation</title>
        <script src="email.js"></script>
    </head>
    <body>
        <span style="padding: 5px;">
            <input type="text" id="email-input" placeholder="Email..."></input>
        </span>
    </body>
</html>

email.js:

var checkEmail = function() {
    var regexp = /BIG_REGEX/;
    var email = document.getElementById('email-input').value;
    if (email === '') 
        removeFrame();
    else if (regexp.test(email))
        drawFrame('green');
    else
        drawFrame('red');
};

var removeFrame = function() {
    var input = document.getElementById('email-input');
    input.parentNode.style.backgroundColor = input.parentNode.parentNode.style.backgroundColor;
};

var drawFrame = function(color) {
    var input = document.getElementById('email-input');
    input.parentNode.style.backgroundColor = color;
};


window.onload = function() {
    document.getElementById('email-input').onkeyup = checkEmail;
};

I want to test validation functionality using CasperJS. Here is my test case:

test/validator.test.js:

var fillEmail = function(browser, email) {
    browser.sendKeys('#email-input', email, {reset: true});
};

var getValidation = function(browser) {
    var color = browser.evaluate(function () {
        return document.getElementById('email-input').parentNode.style.backgroundColor;
    });
    return color;
};

var validate = function(browser, email) {
    fillEmail(browser, email);
    return getValidation(browser);
};

casper.test.begin('Validation testing', function suite(test) {
    casper.start('http://localhost:8000/email.html', function() {
        test.assertEquals(validate(this, 'uskovm@gmail.com'), 'green', 'uskovm@gmail.com');
        test.assertEquals(validate(this, 'vnbgfjbndkjnv'), 'red', 'vnbgfjbndkjnv');
    }).run(function() {
        test.done();
    });

});

But when I run tests using casperjs test test/validator.test.js, there is always error after information about tests:

Unsafe JavaScript attempt to access frame with URL about:blank from frame with URL file:///C:/Users/home/AppData/Roaming/npm/node_modules/casperjs/bin/bootstrap.js. Domains, protocols and ports must match.

What's wrong?

PhantomJS version: 1.9.8

Have you narrowed it down which line causes this? If not, add some console.log and try to narrow it down to one line. — Artjom B., Oct 31 '14 at 09:00
@ArtjomB. This line is printed when test passing is done (after `PASS 2 tests executed in 2.693s, 2 passed...`) — michaeluskov, Oct 31 '14 at 09:03
This is because of some change that was introduced in PhantomJS 1.9.8 and there is a [CasperJS issue](https://github.com/n1k0/casperjs/issues/1068) about it. So [this](http://stackoverflow.com/questions/26608391/using-phantomjs-to-embed-all-images-of-a-webpage) might be related, but since this error comes up when the script finished, I don't see what can be done. — Artjom B., Oct 31 '14 at 09:30
Ok, this happens when the script exits. I don't see that anything can be done for CasperJS to remove those warnings. I created a [GitHub issue](https://github.com/ariya/phantomjs/issues/12697) for the PhantomJS problem. — Artjom B., Nov 01 '14 at 10:03

Recent PhantomJS (1.9.8) introduced this error message. It doesn't cause any real issue, other than confusing log lines when quiting PhantomJS.

It is fixed in unreleased 1.9 branch: https://github.com/ariya/phantomjs/pull/12720

This issue is fixed in phantomjs version 1.9

"phantomjs": "^1.9.9"

for casperJs

casperjs --ssl-protocol=tlsv1 test  run.js

I was getting this same error, so I tried updating to phantomjs 1.9.9 (from 1.9.8). However, I was getting an install error when trying to install 1.9.9, so I down rev-ed to phantomjs 1.9.7, and that fixed this error for me. So, it seems like this is an issue introduced in phantomjs 1.9.8.

Hey there are several workarounds to try and get around this by exiting phantom in a different way such as

   casperjs --ssl-protocol=tlsv1 test  run.js

WHICH DOSE NOT HELP and

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

instead of

this.exit();

Nothing has worked!!!

I tried several different versions of PhantomJS. My output comes in as JSON and after many hours of failed attempts of JSON.parse(stdout)I had to give up. I figured 'F' it I'm just going to handle the 'F'ing error.

so simple before i exit i

this.echo(',{"error":"');

and After I send

this.echo('"}]');

When i get my results back i simply replace all the line breaks and ignore the error

stdout = stdout.replace(/(?:\r\n|\r|\n)/g, '');

Side note: this problem was tried to be fixed with phantom 1.9.9 but instead the focussed on building phantom 2.0 which is not compatible with CasperJS
