HERE Maps Geocoder Autocomplete API CORS Errors

Question

Я пытаюсь реализовать HERE Geocoder Autocomplete API на странице html, следуя примеру https://developer.here.com/documentation/examples/rest/geocoding_suggestions, в результате он показывает мне ошибку CORS. [показано на изображении][1].[1]: https://i.stack.imgur.com/O8duZ.png

      var AUTOCOMPLETION_URL = 'https://autocomplete.geocoder.ls.hereapi.com/6.2/suggest.json',
                ajaxRequest = new XMLHttpRequest(),
                query = '';

            /**
             * If the text in the text box  has changed, and is not empty,
             * send a geocoding auto-completion request to the server.
             *
             * @param {Object} textBox the textBox DOM object linked to this event
             * @param {Object} event the DOM event which fired this listener
             */

            function autoCompleteListener(textBox, event) {
                if (query != textBox.value) {
                    if (textBox.value.length >= 1) {
                        
                        var params = '?' +
                            'query=' + encodeURIComponent(textBox.value) +   // The search text which is the basis of the query
                            '&beginHighlight=' + encodeURIComponent('<mark>') + //  Mark the beginning of the match in a token.
                            '&endHighlight=' + encodeURIComponent('</mark>') + //  Mark the end of the match in a token.
                            '&maxresults=5' +  // The upper limit the for number of suggestions to be included
                            // in the response.  Default is set to 5.
                            '&apikey=' + APIKEY;

                        ajaxRequest.open('GET', AUTOCOMPLETION_URL + params);
                        ajaxRequest.send();
                    }
                }
                query = textBox.value;
            }

            function onAutoCompleteSuccess() {

                clearOldSuggestions();
                addSuggestionsToPanel(this.response);  // In this context, 'this' means the XMLHttpRequest itself.
                addSuggestionsToMap(this.response);

                console.log(this.response);
            }

            function onAutoCompleteFailed() {
                alert('Ooops!');
                console.log(this.response);
            }


            var APIKEY = 'H6XyiCT0w1t9GgTjqhRXxDMrVj9h78ya3NuxlwM7XUs';

            var platform = new H.service.Platform({
                apikey: APIKEY,
                useCIT: false,
                useHTTPS: true
            });

            // Attach the event listeners to the XMLHttpRequest object
            ajaxRequest.addEventListener("load", onAutoCompleteSuccess);
            ajaxRequest.addEventListener("error", onAutoCompleteFailed);
            ajaxRequest.responseType = "json";
