I was trying to fetch JSON data and parse it from another site when I got a error that said
Cross-Origin Read Blocking (CORB) blocked cross-origin response http://a-url with MIME type application/json. See https://www.chromestatus.com/feature/5629709824032768 for more details.
        function fetchdata() {
            // Replace ./data.json with your JSON feed
            fetch('[some-url-with-CORB]').then(response => {
                return response.json();
            }).then(data => {
                // Work with JSON data here
                console.log(data);
            }).catch(err => {
                // Do something for an error here
            });
        }
I intended to get a JSON response and then parse it from there, but CORB prevented me from doing so.
