This is because when there is a fresh page load for a `/todos/42`, the server looks for the file `build/todos/42` and does not find it. The server needs to be configured to respond to a request to `/todos/42` by serving `index.html`. For example, we can amend our Express example above to serve `index.html` for any unknown paths:

```diff
app.use(express.static('./build'));
app.use(express.static(path.join(__dirname, 'build')));

-app.get('/', function (req, res) {

res.sendFile(path.join(__dirname, 'build', 'index.html'));
});
