help: issue with fetching

📚 What are you trying to do? Please describe. I run my vue 3.0 project successfully, but the page source didn’t show my data, and send me a error message; Code

setup() {
    const route = useRoute();
    const data = ref({});
    const { id = "" } = route.value.params;
    const fetchData = async () => {
      let detail = await Api.detail(id);
      detail.content = marked(detail.content);
      data.value = detail;
    };

    const { fetch, fetchstate } = useFetch(async () => {
      await fetchData();
    });
    fetch();
    fetchstate;

    return {
      data,
    };
  },

Error

 ERROR  Error in fetch(): Cannot read property 'data' of undefined                                                                                                            18:17:54

I found the question, It cause by axiox, It maybe used by other library, so I need to create a new instance; const instance = axios.create() My project run successfully, I will read the document carefully next time ! Thank you !

@congyaqwq You shouldn’t need to manually trigger fetch() at all - it will be done by useFetch.
