当用户登录时，我可以获得以下Json数据。
约松

{
    "hubs": [
        "111.com",
        "222.com",
        "333.com",
}

下面的代码部分

console.log(response.data.hubs[0])
  console.log(response.data.hubs[1])
  console.log(response.data.hubs[2])

我可以看到如下URL

"111.com", "222.com", "333.com",

在控制台中。
但是，我使用了dispatch、stores和useSelector，得到了如下错误。

我不知道为什么会出错。
