元素类型无效，需要字符串（对于内置组件）或类/函数（对于复合组件），但得到：object

Question

错误：元素类型无效：需要字符串（对于内置组件）或类/函数（对于复合组件），但得到：object。

检查App的渲染方法。

import React from "react";
import {
  BrowserRouter as Router,
  HashRouter,
  Route,
  Switch,
} from "react-router-dom";
import "./scss/style.scss";

import Routes from "./routes";

const loading = (
  <div className="pt-3 text-center">
    <div className="sk-spinner sk-spinner-pulse"></div>
  </div>
);

function App() {
  // Containers
  const TheLayout = React.lazy(() => import("./containers/TheLayout"));

  // Pages

  // const Register = React.lazy(() => import('./views/pages/register/Register'));
  // const Page404 = React.lazy(() => import('./views/pages/page404/Page404'));
  // const Page500 = React.lazy(() => import('./views/pages/page500/Page500'));
  // const Pistatus = React.lazy(()=> import('./views/theme/pistatus/pistatus'));

  return (
    <div className="App">
      <main>
        <Routes />
      </main>
    </div>
  );
}

export default App;
