我正在尝试设置一个 Meil​​iSearch 索引，以便在我的后端服务器（NodeJS/ExpressJS）启动时填充。下面是我的代码：

const withDB = async (operations, res) => {
try {
    const client = await MongoClient.connect('mongodb://localhost:27017', { useNewUrlParser: true });
    const db = client.db('database-name');

    await operations(db);

    client.close();
} catch (error) {
    res.status(500).json({ message: 'Error connecting to db', error });
}
}

app.listen(8000, async(res) => {
withDB(async (db) => {
    const searchReports = await db.collection('reports').find().limit(500).toArray()
    res.status(200).json(searchReports);
    const searchIndex = new MeiliSearch({ host: 'http://127.0.0.1:7700' })
    searchIndex.index('Reports').addDocuments(searchReports) 
        .then((res) => console.log(res));

}, res)

});

除了我添加任何一个引用“res”的行之外，一切都很好。那时我得到错误：

            res.status(500).json({
                ^

TypeError: Cannot read properties of undefined (reading 'status')
