未捕获的TypeError：e.replace不是fullcalendar中的函数

Question

我在点击日历中的日期时尝试显示模态。点击模式正确显示。但是所有旧事件都丢失了，我收到了错误

Uncaught TypeError: e.replace is not a function
at nt (fullcalendar.min.js:16)
at _ (fullcalendar.min.js:17)
at O (fullcalendar.min.js:17)
at lt.E [as renderEvents] (fullcalendar.min.js:16)
at R (fullcalendar.min.js:16)
at fullcalendar.min.js:16

我在关闭时发现了一个新错误，然后再点击再次显示模态

        $('#modalTitle').html(calEvent.title);

        $('#eventUrl').attr('href',calEvent.url);
        $('#calendarModal').modal();


    }
});
});

我在index.php中包含fullcalendar.min.js
