How to React-Admin Use JsonServer Get My express API "The response to 'getList' must be like { data : [...] }

Question

I use jsonServerProvider But I can not get my express Api data

error code

The response to 'getList' must be like { data : [...] }, but the received data is not an array. The dataProvider is probably wrong for 'getList'

My React-Admin ./dataProvider...

import jsonServerProvider from "ra-data-json-server";
import {fetchUtils} from "react-admin"
import axios from 'axios'

const fetchJson = (url, options = {}) => {
  if (!options.headers) {
      options.headers = new Headers({ Accept: 'application/json' });
  }
  // add your own headers here
  options.headers.set('X-Custom-Header', 'foobar');
  options.headers.set('withCredentials', true);
  axios.defaults.withCredentials = true;
  return fetchUtils.fetchJson(url, options);
}

const dataProvider = jsonServerProvider("http://localhost:5000/periodical/api",fetchJson);

export default dataProvider;

My categoryList...

import * as React from "react";
import {
  List,
  Datagrid,
  TextField,
  EditButton,
  Create,
  Edit,
  SimpleForm,
  SelectInput,
  TextInput,
  DeleteButton,
} from "react-admin";


const CategorysTitle = ({ record }) => {
  return <span>Post {record ? `"${record.title}"` : ""}</span>;
};

export const CategorysList = (props) => (
  <List {...props}>
    <Datagrid>
      <TextField source="id" />
      <TextField source="name" />
      <EditButton />
      <DeleteButton />
    </Datagrid>
  </List>
);

My NodeJS express...

router.route('/').get(async (req, res) => {
    try {
        const data = await CATEGORY.get();
        res.set('Access-Control-Expose-Headers', 'X-Total-Count')
        res.set('X-Total-Count', data)
        console.log(data);
        return res.status(200).json({ data });
    } catch (error) {
        return res.status(500).json({ error });
    }
});
