错误：预期“插入”是字符串，但得到的是primitive.D - MongoDB Atlas、Mongoose

Question

我在尝试使用 Mongoose 在 MongoDB Atlas 中执行 insertMany 操作时遇到问题。我收到的错误消息是：

MongoBulkWriteError: Expected 'insert' to be string, but got primitive.D instead.

我已经尝试通过在连接选项中将 retryWrites 设置为 false 来禁用可重试写入。然而，问题仍然存在。这是相关代码的简化版本

 // Mongoose connection options
const mongooseOptions = {
   retryWrites: false,
};
mongoose.connect(mongoURI, mongooseOptions);

看一下端点👇🏽

router.post('/insertMany', async (req, res) => {
    try {
        console.log(req.body);
        const category = await Category.insertMany(req.body.list);
        res.json(category);
    } catch (error) {
        console.log(error);
        res.status(400).json({ error: error.message });
    }
});

尝试过这个🧐

router.post('/insertMany', async (req, res) => {
    try {
        console.log(req.body);
        let list = req.body.list.map(cat => Category(cat))
        const category = await Category.insertMany(list);
        res.json(category);
    } catch (error) {
        console.log(error);
        res.status(400).json({ error: error.message });
    }
});

请求通过 Postman 发送👇🏽

{
    "list": [
        {
            "name": "Test Category",
            "description": "Test category Desc"
        }
    ]
}

型号👨🏽u200d💻

    // models/Category.js
const mongoose = require('mongoose');

const categorySchema = new mongoose.Schema({
    name: { type: String, unique: true },
    active: { type: Boolean, default: true }, // Added for tracking the active status
    description: String
});

module.exports = mongoose.model('Category', categorySchema, { collection: 'category' });

Answer 1

删除了可选参数

 module.exports = mongoose.model('Category', categorySchema, { collection: 'category' });

到👇🏽

module.exports = mongoose.model('Category', categorySchema);

这有效！但是如何告诉 Atlas 使用用户给定的名称创建集合呢？
