Using fetch to get Google Books API

I did try though I get an error in chrome, about CORE so not sure if there is something I need to add to the code as per below;

const request = async () => {
  const response = await fetch(
    "https://www.googleapis.com/books/v1/volumes?q=isbn:0747532699");
  const json = await response.json();
  let items = json.items;
  console.log(items);
  console.log(json);
};

request();
