我正在尝试使用打字稿进行反应查询教程，但是在获取数据时发生了错误。

代码：

type heroType = {
  id: number;
  name: string;
  alterEgo: string;
};

function QueryDataFetch() {
  const fetchdata = ()=>{ return axios.get("http://localhost:8000/superheroes")}
  const { isLoading, data ,error} = useQuery<heroType[]>(["heros"],fetchdata);

此错误红色 unline 显示在fetchdata

数据：

[
{
"id": 1,
"name": "Batman",
"alterEgo": "Bruce Wayne"
},
{
"id": 2,
"name": "Superman",
"alterEgo": "Clark Kent"
},
{
"id": 3,
"name": "Wonder Woman",
"alterEgo": "Princess Diana"
}
]

错误：

TS2769: No overload matches this call.
