Ace-Editor error when showing StatusBar in Vim mode – Blancer.com Tutorials and projects

I want to show the status bar when using vim mode in Ace editor. There seems to already exist a statusbar extension however using it causes some error. I am using the following code. I am new to JS so any help is appreciated.

<!DOCTYPE html>
<html>

<body>
    <div id="container" style="width: 400px; height: 300px; border: 1px solid grey"></div>
    <div id="status"></div>

    <script src="/static/js/ace-editor/src-noconflict/ace.js" type="text/javascript" charset="utf-8"></script>
    <script src="/static/js/ace-editor/src-noconflict/ext-statusbar.js" type="text/javascript"
        charset="utf-8"></script>

    <script>
        var editor = ace.edit("container");
        editor.session.setMode("ace/mode/golang");
        editor.session.setValue('package mainnnfunc main(){n    fmt.Println("hw")n}');
        editor.setKeyboardHandler("ace/keyboard/vim");

        const sb = ace.require("ace/ext/statusbar");
        var statusBar = sb.StatusBar(editor, document.getElementById("status"));
    </script>
</body>

</html>

The error in the console is
