插入日历时无法执行setId()(用于java的日历api)

我做不到 setId() 插入日历时(java日历api)。

错误请求{“代码”:400,“错误”:[ { “domain”:“全局”, “reason”:“无效” }],“message”:“资源id值无效。”}

我的代码:

private fun insertCalendar(){
    object : Thread() {
        override fun run() {
            val calendar = com.google.api.services.calendar.model.Calendar()
                    .setSummary("Lich hoc ictu")
                    .setDescription("Lich hoc ictu")
                    .setTimeZone("Asia/Ho_Chi_Minh")
                    .setId("calendarictu@group.calendar.google.com")
            service.Calendars().insert(calendar).execute()
            runOnUiThread {
                Toast.makeText(this@MainActivity, "Added", Toast.LENGTH_LONG).show()
            }
        }
    }.start()

}
