How to Fix Matched Leaf Route at Location Does Not Have an Element

When working with React Router, encountering the error message "Matched leaf route at location does not have an element" can be frustrating. This error usually occurs when a matched leaf route is missing an associated element to render. Developers transitioning from earlier versions of React Router DOM may face this issue, especially due to changes in the way route path definitions work in newer versions.

This blog will explain why this error occurs, how to diagnose it, and different approaches to fix it. Whether you're defining a leaf route at location, dealing with missing component prop, or handling a null value by default resulting in an unexpected failure, this article will help you find the correct answer.

Understanding “Matched Leaf Route at Location Does Not Have an Element”

What Causes This Error?

The error "Matched Leaf Route at Location Does Not Have an Element" typically occurs due to:

1. Missing Element in Route Definition: The route at location does not specify an element to render.

2. Incorrect Usage of the component Prop: The component prop anymore is no longer valid in React Router v6.

3. Routes Defined Without an Element: A matched leaf route must have a valid element to be rendered.

4. Mismatched Route Paths: If a route path is defined incorrectly, the default resulting behavior can lead to a missing element.

Example of the Error

The following code snippet illustrates a common mistake:

1import { BrowserRouter as Router, Routes, Route } from "react-router-dom";
2import Home from "./Home";
3import About from "./About";
4
5function App() {
6  return (
7    <Router>
8      <Routes>
9        <Route path="/" component={Home} /> {/* ❌ Incorrect */}
10        <Route path="/about" component={About} /> {/* ❌ Incorrect */}
11      </Routes>
12    </Router>
13  );
14}
15
16export default App;

​

Why This Code Fails

• The component prop is not supported in React Router v6.

• React Router DOM requires the use of element instead of component.

How to Solve the Matched Leaf Route at Location Does Not Have an Element Error

1. Replace component with element

To fix this, modify the route path definitions:

1import { BrowserRouter as Router, Routes, Route } from "react-router-dom";
2import Home from "./Home";
3import About from "./About";
4
5function App() {
6  return (
7    <Router>
8      <Routes>
9        <Route path="/" element={<Home />} /> {/* ✅ Correct */}
10        <Route path="/about" element={<About />} /> {/* ✅ Correct */}
11      </Routes>
12    </Router>
13  );
14}
15
16export default App;

​

Now, each leaf route at location has a valid element to render.

2. Handle Default Resulting Behavior Properly

If a route path is not explicitly assigned an element, it will trigger the error. You can define a default fallback element to avoid a null value by default resulting in an error:

1import { BrowserRouter as Router, Routes, Route } from "react-router-dom";
2import Home from "./Home";
3import About from "./About";
4import NotFound from "./NotFound";
5
6function App() {
7  return (
8    <Router>
9      <Routes>
10        <Route path="/" element={<Home />} />
11        <Route path="/about" element={<About />} />
12        <Route path="*" element={<NotFound />} /> {/* ✅ Default fallback */}
13      </Routes>
14    </Router>
15  );
16}
17
18export default App;

​

Now, when an undefined route path is accessed, the NotFound component is rendered instead of causing a null value error.

Handling Nested Routes Correctly

Incorrect Nested Route Definition

In React Router DOM, a common mistake when defining nested routes is forgetting to provide an element for the parent route. This can lead to the matched leaf route at location not having an element error.

1import { BrowserRouter as Router, Routes, Route } from "react-router-dom";
2import Dashboard from "./Dashboard";
3import Settings from "./Settings";
4
5function App() {
6  return (
7    <Router>
8      <Routes>
9        <Route path="/dashboard">
10          <Route path="settings" element={<Settings />} /> {/* ❌ Parent route missing element */}
11        </Route>
12      </Routes>
13    </Router>
14  );
15}
16
17export default App;

​

Correct Way to Define Nested Routes

To fix this issue, the parent route must contain an element that acts as a wrapper for child routes:

1import { BrowserRouter as Router, Routes, Route } from "react-router-dom";
2import Dashboard from "./Dashboard";
3import Settings from "./Settings";
4
5function App() {
6  return (
7    <Router>
8      <Routes>
9        <Route path="/dashboard" element={<Dashboard />}>
10          <Route path="settings" element={<Settings />} /> {/* ✅ Correct */}
11        </Route>
12      </Routes>
13    </Router>
14  );
15}
16
17export default App;

​

This ensures that the matched leaf route inside /dashboard works correctly.

React Router DOM: Handling Null Values

Dealing with a Null Value by Default Resulting in an Error

Sometimes, missing components or dynamic routes may result in a null value by default. The following code ensures that a route at location does not fail due to missing elements:

1import { BrowserRouter as Router, Routes, Route } from "react-router-dom";
2
3function App() {
4  return (
5    <Router>
6      <Routes>
7        <Route path="/" element={<h1>Home</h1>} />
8        <Route path="/dynamic" element={null || <h1>Dynamic Page</h1>} /> {/* ✅ Prevents null */}
9      </Routes>
10    </Router>
11  );
12}
13
14export default App;

​

This approach ensures that a null value does not break the render process.

Final Thoughts

The error "Matched Leaf Route at Location Does Not Have an Element" occurs due to incorrect route path definitions, missing elements, or improper usage of React Router DOM. Fixing this involves updating route definitions, ensuring each matched leaf route has an element, and properly handling null values.

By applying these solutions, the default resulting behavior of React Router will work smoothly, preventing errors and ensuring a seamless user experience.
