我正在尝试学习mongodb CRUD操作和node express js。

当我尝试去‘http://localhost:5000/service’它抛出以下错误：

D:Projects_WebDevBackEndserver-genius-car-servicenode_modulesmongodblibcmapconnection.js:207
                    callback(new error_1.MongoServerError(document));
                             ^

[nodemon] app crashed - waiting for file changes before starting...

代码：`

async function run() {
    try {
        await client.connect();
        const serviceCollection = client.db('genius-car').collection('service');

        app.get('/service', async (req, res) => {
            const query = {};
            const cursor = serviceCollection.find(query);
            const services = await cursor.toArray();
            res.send(services)
        });

    } finally {
        //
    }

}
run().catch(console.dir);`
