Not able to render the SVG icons on google cloud

[nehulagr]

Hello, I am using your library for the first time in one of my website https://www.enrich.asia. I am trying to render it, which is working fine on local system but not working at all on google cloud. Don't know where is the issue. Here is the code where its getting stuck

if (xhr === undefined) {
                            Request = createRequest(base);
                            if (Request !== undefined) {
                                xhr = new Request();
                                cache[base] = xhr;
                                xhr.onload = onloadFunc(xhr);
                                xhr.onerror = onErrorTimeout(xhr);
                                xhr.ontimeout = onErrorTimeout(xhr);
                                xhr.open("GET", base);
                                xhr.send();    <-------------------------------On this line
                                inProgressCount += 1;
                            }
                        }

Can you tell me any idea about it?
