How can I fix the missing element error for the '/dashboard' route when upgrading to React Router v7?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm upgrading from React Router v6 to v7 and encountering the following error when accessing http://localhost:30000/dashboard:

Matched leaf route at location "/dashboard" does not have an element or Component. This means it will render an <Outlet /> with a null value by default resulting in an "empty" page. Error Component Stack
  at Routes (react-router.js?v=5c7cb654:6100:3)
  at RequireAuth (authContext.tsx:84:31)
  at SidebarProvider (sidebarContext.tsx:13:35)
  at AuthProvider (authContext.tsx:35:32)
  at Router (react-router.js?v=5c7cb654:6043:13)
  at BrowserRouter (react-router.js?v=5c7cb654:8070:3)
  at App (App.tsx:12:51)

I followed the upgrade guide but still see this error. Below is my current router setup:

JAVASCRIPT
import { BrowserRouter, Navigate, Route, Routes } from "react-router";
import AdminApp from "./AdminApp";
import DashboardApp from "./DashboardApp";
import { AuthProvider, RequireAuth } from "./context/authContext";
import NotificationContext, {
  useNotification,
} from "./context/notificationContext";
import { SidebarProvider } from "./context/sidebarContext";
import Notification from "./ui/Notification";

const App = () => {
  const [{ show, severity, message }, dispatch] = useNotification();

  return (
    <BrowserRouter>
      <AuthProvider>
        <NotificationContext.Provider value={dispatch}>
          <SidebarProvider>
            <RequireAuth>
              <Routes>
                <Route
                  path="/"
                  element={<Navigate to="dashboard" replace />}
                />
                <Route path="admin">
                  <Route path="*" element={<AdminApp />} />
                </Route>
                <Route path="dashboard">
                  <Route path="*" element={<DashboardApp />} />
                </Route>
              </Routes>
            </RequireAuth>
          </SidebarProvider>
          {show && <Notification type={severity} text={message} />}
        </NotificationContext.Provider>
      </AuthProvider>
    </BrowserRouter>
  );
};

export default App;

I've read that for nested routes in React Router v7, the parent route must include an element (or an ). What changes should I make to resolve this error?

The error indicates that the matched route (in this case, the "dashboard" route) is a leaf (i.e., a final match) but it doesn’t have an element attached to it. In React Router v7, if you nest routes, the parent route must either provide an element (often an if you don’t have a specific UI to render) or you need to flatten the route structure.

There are two common solutions:

1. Remove the Nested Parent Route

If you don't need a separate layout or wrapper for the dashboard, you can combine the parent and child routes. Replace the nested "dashboard" route with a single route that matches everything under it. For example:

JAVASCRIPT
<Routes>
  <Route path="/" element={<Navigate to="dashboard" replace />} />
  <Route path="admin/*" element={<AdminApp />} />
  <Route path="dashboard/*" element={<DashboardApp />} />
</Routes>

This way, the "dashboard" route always has an element (<DashboardApp />) and the wildcard (*) will correctly match any nested paths.

2. Provide an Element for the Parent Route

If you intend to have nested routes under "dashboard" and want to keep the current nested structure, then the parent route (with path "dashboard") must include an element that renders its children. In many cases, you can simply use the <Outlet /> component from React Router:

JAVASCRIPT
import { Outlet } from "react-router";

<Routes>
  <Route path="/" element={<Navigate to="dashboard" replace />} />
  <Route path="admin">
    <Route path="*" element={<AdminApp />} />
  </Route>
  <Route path="dashboard" element={<Outlet />}>
    <Route path="*" element={<DashboardApp />} />
  </Route>
</Routes>

The <Outlet /> acts as a placeholder for the nested routes. Now, when you visit /dashboard, React Router will match the parent route with <Outlet /> and render the child route element (<DashboardApp />) accordingly.

Choose the solution that best fits your intended routing structure. If you only have one component for each top-level path, the first approach (flattening the route structure) is usually simpler.

In the original dashboard route you didn't specify an element, so it considered as wildcard route because you mentioned as *.

so provide an element for dashboard route

JSX
 <Route path="dashboard">
   <Route path="*" element={<DashboardApp />} />
 </Route>

Instead of the above one, you can try anyone of the below:

 <Route path="dashboard/*" element={<DashboardApp />} />

 **Or**  

 <Route path="dashboard">
   <Route index element={<DashboardApp />} />
 </Route>

**Or if you have nested routes try this**  
<Route path="dashboard">
    <Route index element={<DashboardApp />} /> {/* Matches /dashboard */}
    <Route path="header" element={<Header />} /> {/* Matches /dashboard/header*/}
    <Route path="banner" element={<Banner />} /> {/* Matches /dashboard/banner*/}
  </Route>

The DashboardApp will be rendered on any "/dashboard/*" sub-route, i.e. "/dashboard/a", "/dashboard/b", etc, but there is apparently no route matching exactly the "/dashboard" route path.

If you would like for DashboardApp to also be rendered on exactly "/dashboard" then also specify this to be an index route.

Example:

JSX
<Route path="dashboard">
  <Route
    index    // <-- matches "/dashboard" exactly
    path="*" // <-- matches any "/dashboard/*" path
    element={<DashboardApp />}
  />
</Route>

If Dashboard is implemented in such a way there there is no actual content to render on exactly "/dashboard" then update the redirect to navigate to a route that does exist.

Example:

JSX
const DashboardApp = () => (
  <>
    ...
    <Routes>
      <Route path="a" element={<DashboardA />} />
      <Route path="b" element={<DashboardB />} />
      <Route path="c" element={<DashboardC />} />
      ...
    </Routes>
  </>
);

JSX
<Routes>
  <Route
    path="/"
    element={(
      <Navigate
        to="dashboard/B" // <-- redirect to existing route
        replace
      />
    )}
  />
  <Route path="admin">
    <Route path="*" element={<AdminApp />} />
  </Route>
  <Route path="dashboard">
    <Route path="*" element={<DashboardApp />} />
  </Route>
</Routes>
