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

I keep getting the error: "The parent was not an HTML element" with the statement "let ul = removeMe.parentNode;" Why?

The variable removeMe in the statement removeMe = document.querySelector(".remove_me"); should contain the object describing the li element with class "remove_me". I should then be able to traverse to the parent node "ul" with .parentElement property of this object. Where am I going wrong here?

var removeMe = document.querySelector('.remove_me');
let ul = removeMe.parentElement;
var parent;
<!DOCTYPE html>
        <title>Parent Traversal</title>
    <link rel="stylesheet" href="style.css" />
            <li class="remove_me">Good bye!</li>
        <script src="app.js"></script>

Hey David, for this challenge you'll just want to select the element you want to remove; you've done that with your first line of code. Then you need to select the parent element. Then use the removeChild() method to remove the element from its parent, like so:

var removeMe = document.querySelector('.remove_me');
var parent = removeMe.parentNode;

Hope this helps
