JavaScript jQuery Basics Working with jQuery Collections The .each() method

Unexpected AST node type encountered

So I'm working on this relatively basic problem and just adding inputs to the <li> tags in index.html. For some reason, the checker is not accepting the inputs. I know it works since the preview shows the checkboxes showing up.

Of course the issue is in the fact that my code is not exactly what is wanted; however, for the life of me, I can't figure out what is being done wrong. The prompt was:

Inside the jQuery each() method, use prepend() to add an '<input type="checkbox"/>' to the beginning of each list item. Use the this keyword, so the callback function doesn't need any arguments.

Thanks!

index.html 
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <h2>My Favorite Things</h2>

    <ul class="favorite-things">
        <li>Kittens</li>
        <li>Rainbows</li>
        <li>Unicorns</li>
        <li>Sprinkles</li>
    </ul>

    <script
    src="jquery-3.2.1.min.js"></script>
    <script src="app.js"></script>
</body>
</html>
app.js 
$('.favorite-things li').each(function() {
  $(this).prepend( $('<input type="checkbox"/>') );
});

Your code should actually work. Great job! I think the error you're seeing is actually a bug in the challenge checker, and it's failing to parse your code properly. I'd send an email to support to let them know about it. However, when I removed the $() around the input element in your code, and just passed that string directly to the prepend method, the challenge let me through just fine.
