React Query's .isSuccess error occurs when I use axios to make a get request

Question

const searchInvoiceList = async (
  plantLoc: string,
  invoiceOption: string
) => {
  let data: InvoiceData[] = [];
  await axios
    .get(`${linkURL}inv/getControlList/${plantLoc}/${invoiceOption}`)
    .then((response) => {
      data = response.data.sqlData;
    })
    .catch((error) => console.error(error));
  return data;
};

  const fetchInvoices = useQuery({
    queryKey: [
      "invoiceData",
      plantLocationOptionChecked.value,
      invoiceOptionChecked.value,
    ],
    queryFn: () =>
      searchInvoiceList(
        plantLocationOptionChecked.value,
        invoiceOptionChecked.value
      ),
    enabled: false,
    retry: 0,
  });
  if (fetchInvoices.isSuccess) {
    if (fetchInvoices.data.length === 0) {
      toast.error("搜索结果为空");
    }
    setFetchedInvoiceData(fetchInvoices.data);
  }
  if (fetchInvoices.isError) {
    console.log(fetchInvoices.error);
  }

我有一个按钮，有一个onClick事件，调用fetchInvoices.refetch()时出现错误。第一个错误是“重新渲染次数过多。React限制了渲染次数以防止无限循环。”如果我去掉setFetchedInvoiceData(fetchInvoices.data);并且数组返回为0，它会触发我的react-hot-toast函数toast.error("搜索结果为空");但然后我会收到警告“在渲染不同组件（App）时无法更新组件（Ie）”。我做错了什么，如何修复这个问题？

It's hard to give you the best solution without looking at your entire component's code, but currently here I see that you are getting fetchInvoices.isSuccess on every re-render Running condition, the best way to solve it is to add it to useEffect like this:

useEffect(() => {
      if (fetchInvoices.isSuccess) {
        if (fetchInvoices.data.length === 0) {
          toast.error("搜索结果为空");
        }
        setFetchedInvoiceData(fetchInvoices.data);
      }
     if (fetchInvoices.isError) {
       console.log(fetchInvoices.error);
     }
   }, [fetchInvoices.isSuccess, fetchInvoices.isError])
