mongodb - 为什么猫鼬的 find() 给出了这个奇怪的结果，带有对象数组

Question

我对猫鼬做了一个简单的查找查询，它也返回了结果，但它给出了对象数组的结果（这不是问题），但它有对象数组，对象包含它的内部函数和属性，我认为与我的需要无关，因为我只想要数据库中的查询结果。

const Joi = require('joi');
const Session = require('../models/session.model');

exports.tokenUtility = async (req, res, next) => {
    const {token, contactNumber, query} = req.body;
    if(token) {
        try{
            const session = await Session.find({token});
            console.log("Found Session", session);
        } catch(error) {
            next(error)
        }
    } else {
        console.log("in token util, token is not present");
        const generatedToken = (Math.random()*1e18).toString(36);
    }
}

它从Found Session的输出中给了我这个结果
