Fancybox - The requested content cannot be loaded - load fancybox from array

Question

I am trying to load a fancybox through an array, however I am having problems, I get the following error message: The requested content cannot be loaded.

$(document).ready(function(){
    $('.project-trigger').on('click', function(e){
        e.preventDefault();

        var el = $(this),
            images = el.siblings('.project-images').find('a'),
            formated = [];

        $.each(images, function(i, e){
            formated.push({
                'href': $(e).attr('href')
            });
        });

        $.fancybox.open(formated);
    });
});

.project-images{
  display: none;
}

<a href="#" class="project-trigger">Click me</a>
<ul class="project-images">
  <li>
    <a href="http://via.placeholder.com/800x600">
      <img src="http://via.placeholder.com/800x600">

    </a>
  </li>
</ul>

Any idea why this is happening?

Would you try changing 'href': $(e).attr('href') to 'src': $(e).attr('href') ?

$(document).ready(function(){
    $('.project-trigger').on('click', function(e){
        e.preventDefault();

        var el = $(this),
            images = el.siblings('.project-images').find('a'),
            formated = [];

        $.each(images, function(i, e){
            formated.push({
                'src': $(e).attr('href')
            });
        });

        $.fancybox.open(formated);
    });
});

.project-images{
  display: none;
}
