Node.js版本：v18.15.0 mongoose：7.1.1
当我通过PostMan发送数据时，它很好地保存了所有内容并完成了它的工作，但我在控制台上得到了这个错误。

app.post('/product', async (req, res) => {
    try {
        const singleProduct = await product.create(req.body)
        res.sendStatus(200).json(singleProduct)
    } catch (error) {
        console.log(error.message);
        res.sendStatus(500).json({ message: error.message })
    }

通过 Postman 投递数据后，显示以下错误

Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client
