cf properties are undefined in react-router example

I used the [same example](https://github.com/cloudflare/templates/blob/main/react-router-starter-template/workers/app.ts) and deployed on a worker

```

export default {
fetch(request, env, ctx) {
return requestHandler(request, {
cloudflare: { env, ctx },
});
},
} satisfies ExportedHandler;
```

The cf properties are undefined.

```
export const loader = async ({
context,
request,
}: Route.LoaderArgs): Promise => {
const { env, ctx } = context.cloudflare;
const ip_address = request.headers.get("CF-Connecting-IP");

console.log("CF Props", request.cf);
});
```
