RTK 查询结果不可解析 JSON

我这样做是为了学习 React-toolkit：

import { createApi, fetchBaseQuery } from "@reduxjs/toolkit/query/react";

export const getIPv4AddressApi = createApi({
  reducerPath: "getIPv4Address",
  baseQuery: fetchBaseQuery({
    baseUrl: "https://ip4.8n1.org/",
  }),
  endpoints: builder => ({
    getIPv4Address: builder.query<string, void>({
      query: () => "",
    }),
  }),
});

export const { useGetIPv4AddressQuery } = getIPv4AddressApi;

运行时，我收到错误

{"status":"PARSING_ERROR","originalStatus":200,"data":"xxx.xxx.xxx.xxx\n","error":"SyntaxError: Unexpected token . in JSON at position 6"}

我怎样才能返回整个响应而不尝试 JSON 解析？非常感谢

See 解析响应 https://redux-toolkit.js.org/rtk-query/api/fetchBaseQuery#parsing-a-response

  endpoints: builder => ({
    getIPv4Address: builder.query<string, void>({
      query: () => "",
      responseHandler: "text"
    }),
  }),
