URL for "fetch remote data" has a 404

[rainerlonau]

In the sample code the URL is not available:

var asyncResult = await javascriptRuntime.evaluateAsync("""
                fetch('https://raw.githubusercontent.com/abner/flutter_js/master/cxx/quickjs/VERSION').then(response => response.text());
              """);

There´s still a response text -> "404: Not Found". But I think that´s not the original outcome of this example?
