SP2013 Application with SharePoint Support Modal Dialog Error: Cannot read 'hiddenButtonValueBeforeDialog'

Question

I'm just trying to prove the concept of displaying a modal dialog on my application page for SharePoint. I believe that I have included the necessary js libraries, and I give it more than enough time to load the libraries before performing its function. Received error:

Unable to read property "hiddenButtonValueBeforeDialog" undefined

I believe that I need libraries:

<script type="text/javascript" src="/_layouts/15/init.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.runtime.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.js"></script>
<script type="text/javascript" src="/_layouts/15/SP.UserProfiles.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.core.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.ui.dialog.js"></script>

JavaScript:

function showDialog() {

var optDict = {
    width: 800,
    height: 500,
    url: 'http://www.google.com',
    title: "Upload your file"
};

try {
    SP.UI.ModalDialog.showModalDialog(optDict);
}
catch (err) {
    alert(err.message);
}

    return false;
}
