如何获取一个陌生人的QQ等级？

如何通过QQ号获取一个陌生人(对方从未发过消息)的QQ等级？
我想通过此方法来判断申请进群的人等级是否大于指定值，避免小号。
我尝试使用此方法：

getCurrentBot().getStranger(event.getFromId()).queryProfile().getQLevel()

但是会报错：

java.lang.NullPointerException: Cannot invoke "net.mamoe.mirai.contact.Stranger.queryProfile()" because the return value of "net.mamoe.mirai.Bot.getStranger(long)" is null
