代码出问题了，求修改

Question

昨天写了个代码，一调试就出错，代码如下↓

/*! 
 * Time JavaScript Library v1.2.5

 * Time:2023-04-12T15:11Z
 */
;(function(global, factory) {
    typeof exports === 'object' && typeof module !== 'undefined' ? module.exports = factory() :
        typeof define === 'function' && define.amd ? define(factory) :
        global.time = factory();
}(this, (function(config) {
    if (typeof config === "object") {
        if (config.type == "time") { //time
            function formatDate(n) {
                date = new Date()
                const r = new Date(date);
                var table = { // create timetable
                    'M+': r.getMonth() + 1, // months
                    'd+': r.getDate(), // dates
                    'h+': r.getHours(), // hours
                    'm+': r.getMinutes(), // minutes
                    's+': r.getSeconds(), // seconds
                    'S+': r.getMilliseconds() //Miliseconds
                };
                if (/(y+)/.test(n)) { //regex
                    n = format.replace(RegExp.$1, (r.getFullYear() + '')
                        .substr(4 - RegExp.$1.length));
                }
                for (var str in table) {
                    if (new RegExp('(' + str + ')')
                        .test(n)) {
                        n = format.replace(RegExp.$1, (RegExp.$1.length === 1) ? (table[str]) : (('00' + table[str])
                            .substr(('' + table[str])
                                .length))); //replace
                    }
                }
                return n;
            }
            return formatDate(config.format)
        } else if (config.type == "timestamp") { //timestamp
            return new Date()
                .getTime();
        }
    } else {
        throw new Error("Param 'config' is not an object"); //error
    }
})));

一直报错，怎么办？
求修改，在 线 等，很着急!
