CastError: Cast to ObjectId failed for value "cover.css"

Question

我尝试使用 NodeJS 和 express 在我的 mongoDB 中保存新数据。 Cover.css 来自 Bootstrap。我通过在我的架构中添加 _Id 找到了解决方案，但我需要让 mongo 成为 _Ids。我无法理解这个错误。通常，如果我没有在我的模式中提及 _Id，mongoose 将创建一个。但是在这个错误中，似乎我必须手动发送一个 Id。我不知道为什么在这里

CastError: Cast to ObjectId failed for value "cover.css" at path "_id" for model "ProductModel"
 messageFormat: undefined,
  stringValue: '"cover.css"',
  kind: 'ObjectId',
  value: 'cover.css',
  path: '_id',
  reason: Error: Argument passed in must be a single String of 12 bytes or a string of 24 hex characters

还有我的代码：

const express = require('express')
var ProductModel = require('./../models/article')
const router = express.Router()

router.get('/new', (req, res) => {
    res.render('products/new', { product: new ProductModel() })
})
router.get('/:id/', async (req, res) => {
    var product = await ProductModel.findById(req.params.id)
    res.render('products/show', { article: product })
router.post('/', async(req, res) => {
    let product = new ProductModel({
        
        Type: req.body.Type,
        Boitier: req.body.Boitier,
        Marque: req.body.Marque,
        Modele: req.body.Modele,
        Annee: req.body.Annee,
        Poids: req.body.Poids,
        Capteur: req.body.Capteur,
        Resolution: req.body.Resolution,
        ISO: { min: req.body.min, max: req.body.max },
        Dimensions: { Hauteur: req.body.Hauteur, Longueur: req.body.Longueur, Profondeur: req.body.Profondeur },
        Charge: req.body.Charge,
        Monture: req.body.Monture,
        Connectique: { USB: req.body.USB, HDMI: req.body.HDMI, mic: req.body.mic, priseCourant: req.body.priseCourant },
        Puissance: req.body.Puissance,
        Temperature: req.body.Temperature,
        Lampe: req.body.Lampe,
        Focale: req.body.Focale
    })
    try {
       product = await product.save()
        res.redirect(`/products/${product.id}/`) 
    } catch (e) {
        res.render('/products/new', { article: product })
        res.send('HUM... embarrassant')
        console.log(e)
    }
    
})
