passport.js 错误：无法将用户序列化到会话中

Question

我在这里使用 Nodejs Mongoose 但是当我尝试替换 Callback 以承诺时它给了我一个错误（无法将用户序列化到会话中）我该怎么办？

我正在使用 passport.serializeUser 和 passport.deserializeUser 但它给出了这个错误

    const passport = require('passport');
const DiscordStrategy = require('passport-discord');
const User = require('../database/schemas/User');

passport.serializeUser((user, done) => {
    done(null, user.discordid)
})

passport.deserializeUser(async (discordId, done) => {
    try {
        const user = await User.findOne({discordId});
        return user ? done(null, user): done(null, null);
    } catch (err) {
        console.log(err)
        done(err, null)
    }
});

passport.use(new DiscordStrategy({
    clientID: process.env.DASBOARD_CLIENT_ID,
    clientSecret: process.env.DASBOARD_CLIENT_SECRET,
    callbackUrl: process.env.DASBOARD_CALLBACK_URL,
    scope: ['identify','guilds'],
}, async (accessToken, refreshToken, profile, done) => {
    const {id, username, discriminator, avatar, guilds} = profile;
    try{
        const findUser = await User.findOneAndUpdate(
            { discordId: id }, 
            {
            discordTag: `${username}#${discriminator}`,
            avatar,
            guilds,
        }, 
        {new: true});
        if ( findUser ) {
            console.log('++')
            return done(null, findUser);
        } else {
            const newUser = await User.create({
                discordId: id,
                discordTag: `${username}#${discriminator}`,
                avatar,
                guilds,
            })
            return done(null, newUser)
        }
    } catch(err){
        console.log(err);
        return done(err, null)
    }
})
);

这是给控制台的错误。我该怎么办？

据此https://mongoosejs.com/docs/promises.html#built-in-promises

如果你要使用async/await，你需要添加.exec()

const user = await User.findOne({discordId}).exec();

const findUser = await User.findOneAndUpdate(
    { discordId: id }, 
    {
        discordTag: `${username}#${discriminator}`,
        avatar,
        guilds,
    }, 
    {new: true}).exec();

const newUser = await User.create({
    discordId: id,
    discordTag: `${username}#${discriminator}`,
    avatar,
    guilds,
}).exec();
