I am new to Azure functions. Is there a way to use one function to represent 2 scenarios: No ID or with an ID? The code below give a 404 on No ID. Thanks!

No ID: http://localhost:7071/api/orders/

With ID: http://localhost:7071/api/orders/21345678654/

app.http('orders', {
methods: ['GET', 'POST'],
authLevel: 'anonymous',
route:'orders/{id}',
handler: async (request, context) => {
    context.log(`Http function processed request for url "${request.url}"`);

    const name = request.query.get('name') || await request.text() || 'world';

    return { body: `Hello!!!!, ${name}!` };
    }
});
