Problem with my code

I feel like this code is correct, but I keep getting an error stating they were expecting three items, not zero. What am I missing?

js/app.js 
let navigationLinks = document.getElementsByTagName('nav a');
let galleryLinks;
let footerImages;
index.html

This is the question:

In the following tasks you'll be required to select various elements on the index.html page. In the app.js file on line 1, select all links in the nav element and assign them to navigationLinks.

Are you sure you called the right function?

Instead of a single tag name, your argument to getElementsByTagName has two terms separated by a space, which looks like a css-style descendant selector.

Did you perhaps intend to call querySelectorAll instead?
