Uncaught Error: [About] is not a ＜Route＞ component. All component children of ＜Routes＞ must be a ＜Ro

When I put react-router-dom from v5 Upgrade to v6, This error message appears .

My code ：

index.js File code

import React from "react"
import ReactDOM from "react-dom"
import "./assets/main.css"
import App from "./App"
import { BrowserRouter } from "react-router-dom"
import { AuthContextProvider } from "./context/AuthContext"

ReactDOM.render(
  <React.StrictMode>
    <AuthContextProvider>
      <BrowserRouter>
        <App />
      </BrowserRouter>
    </AuthContextProvider>
  </React.StrictMode>,
  document.getElementById("root")

export default App

Solution

stay v6 in , You should treat components as “ Elements ” Pass on , Like this ：

<Route path="/" element={<Dashboard/>}>

Or protected route ：

<Route
 path="home"
 element={
   <ProtectedRoute user={user}>
   <Home />
   </ProtectedRoute>
      }
    />
    ...
  </Routes>
