JavaScript JavaScript and the DOM (Retiring) Traversing the DOM Child Traversal

Can you help me understand why this code isn't working?

I run this on my personal computer and I see the p elements changing to blue. I passed the two prior test, but now I get an error telling me a prior test is breaking. scratching head

app.js
const section = document.querySelector('section');
let paragraphs = section.children;

for(p of paragraphs) {
  p.style.color = "blue";
}
index.html
<!DOCTYPE html>
<html>
    <head>
        <title>Child Traversal</title>
    </head>
    <body>
        <section>
            <p>This is the first paragraph</p>
            <p>This is a slightly longer, second paragraph</p>
            <p>Shorter, last paragraph</p>
        </section>
        <footer>
            <p>&copy; 2016</p> 
        </footer>
        <script src="app.js"></script>
    </body>

I'm not sure what the issue could be. Maybe it's workspaces and the for...of loop? A normal for loop will work. Wish I could figure it out with for...of though. Also, scratching head..

for (let i = 0; i < paragraphs.length; i++) {
  paragraphs[i].style.color = "blue"
}

Yeah, the standard for loop works, so this might be a bug for Treehouse to investigate.
