You are using a class for multiple elements which is why undefined is shown. Among many ways, I will discuss two here, you have to either use indices with classes if using queryselector to get the correct element or use an ID to select the input element. Here I have used ID to get the input searchbox. See the following code:
const moviesearchEngine = () => {
let searchBox = document.querySelector('#searchBoxInput');
console.log(searchBox.value)

</html>Your div <div class="searchBox"> also contain a class "searchBox" so it selected that.
Fixed: Add an input selector after class selector.
const moviesearchEngine=()=>{
let searchBox = document.querySelector('.searchBox input');
console.log(searchBox.value)
