Visiting before login URL is incorrect after callback

Help
1

Hello. I have a React project and I used React SPA login implementation from here Auth0 React SDK Quickstarts: Login.

Have this routing in my app

<Router>
     <Switch>
        <PrivateRoute path="/somedetail/:id" component={SomeDetail} />
    </Switch>
</Router>

Let’s suppose user on this page
http://localhost:3000/somedetail/**1** and later decided to go to http://localhost:3000/somedetail/**2** by editing an url in a browser and hitting Enter. Login page immediately appears and a user successfully logs in. Callback should put to a browser URL the URL that was before login page, which is http://localhost:3000/somedetail/**2** but instead I see http://localhost:3000/exchangedetail/:id in browser.

Can you please say what I am doing wrong?
