What's this error in my react project on my codesandbox?-CodePudding

I get this error in my project on Codesandbox. While it doesn't get an error on Webstorm:

Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

See my project: https://codesandbox.io/s/practical-pateu-hptsrx

But I exported all my components. Any idea?

CodePudding user response：

Switch is no longer supported in router v6, you can use Routes instead and use Element as attribute instead of component.

import { BrowserRouter as Router, Route, Routes } from "react-router-dom";

<Routes>
    <Route path="/" element={<Home/>} />
    <Route path="/create" element={<Create />} />
</Routes>
