var currentUserId = currentUser.id;

问题情况：

TypeError: Cannot read property 'id' of null

Answer 1

加个延时，看看是不是请求没有回来。

    var currentUser = Bmob.User.current();
    setTimeout(() => {
      var currentUserId = currentUser.id;
      console.log(currentUserId);
    }, 4000);

如果延时也没用，你的配置项也都正确，那就是 bmob 这个东西的问题。不是你的问题。
