Was expecting 3 links not 0

I keep getting this error. I tried several ways to solve this, like the querySelectorAll or the Id selector. Nothing I tried works.

js/app.js 
let navigationLinks = document.getElementsByClassName("navLink");
let galleryLinks;
let footerImages;
index.html

Don't change any HTML. The whole point of the exercise is to select things as they are. The HTML is provided solely for examination, and I suspect that the validation ignores any changes made to it.

Then, to select the links inside the nav, you can either chain selector functions together, or use one that can take a CSS-style descendant selector.
