node.js - 即使在转换为 ObjectId 后，转换为 ObjectId 的值也失败

Question

以下代码从供应商集合中的员工数组中提取员工

await new VendorManager()
                .update(
                    { employee: mongoose.Types.ObjectId(id) },
                    { $pull: { employee: mongoose.Types.ObjectId(id) } }
                );

字符串转换为**mongoose.Types.ObjectId**但仍然出现错误

error: "Cast to ObjectId failed for value "{ employee: 5c80c16e0c253823fc44332a }" at path "_id" for model "Vendor""

更新功能之前我已经测试过了

mongoose.Types.ObjectId.isValid(id)

它也返回true。

Vendor Schema

name: {
    type: String
},
employee: [{
    type: mongoose.Schema.Types.ObjectId,
    ref: 'Employee'
}],
created_by: {
    type: String
},
updated_by: {
    type: String
},

仅查看错误消息，更新函数的第一个参数似乎应该是 ObjectId，而不是形状如下的数据:

{ employee:ObjectId }

因此，当您尝试将上述对象转换为 ObjectId 时，会出现 super 有用的错误:

error: "Cast to ObjectId failed for value "{ employee: 5c80c16e0c253823fc44332a }" at path "_id" for model "Vendor""
