Task solution not working

To fetch all the "li" within the <nav> tag, I am trying these methods,

  1. let navigationLinks = document.querySelector('nav>ul').getElementsByTagName('li');
  2. I tried to assign a ID = 'foo' to the <ul> element and then I tried this code, let navigationLinks = document.getElementById('foo').getElementsByTagName('li'); Both of these methods are working fine in browser console, but somehow throwing error in treehouse worspace. Please suugest.
js/app.js 
let navigationLinks = document.querySelector('nav>ul').getElementsByTagName('li');
let galleryLinks;
let footerImages;

Hey! The task doesn't want you to fetch all the 'li' elements, but the links inside of them. 

let navigationLinks = document.querySelectorAll("nav ul li a");
