对于模型 "wallet" 的路径“_id”中的值 "me",转换为 ObjectId 失败

Cast to ObjectId failed for value "me" at path "_id" for model "wallet"

How are you all, I want to get a user's data in a node. Means all the data of a single user. Like this is one register data and the other is of payment. Now in this I want to get all the payments of how much a user has paid. I have tried this. But this error is coming Maybe I am not able to write the code correctly. So please guide me.

获取用户支付方式

router.get('/me', auth, async (req, res) => {
    UserWallet.find()
        .select("user", " id user")
        .populate("user ", "_id user")
        .exec()
        .then(result => {
            res.json({ result })
        })
        .catch(error => {
            console.error(error.message)
            res.status(500).send('Server Error')
        })
});

Post method of user payments

router.post(
    '/payment/add',
    async (req, res) => {
        try {
            const user = await users.findById(req.user.id).select('-password');
            const { bankName, tranferRefCode, amount } = req.body;
            const newPayment = new UserWallet({
                bankName,
                tranferRefCode,
                amount,
                username: user.username,
                avatar: user.avatar,
                user: req.user.id
            });
            await newPayment.save().then(payment => {
                res.json({ newPayment: payment })
            })
        } catch (err) {
            console.error(err.message);
            res.status(500).send('Server Error');
        }
    }
);

Schema of user payment

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const walletSchema = new Schema({
    user: {
        type: Schema.Types.ObjectId,
        ref: 'user'
    },
    bankName: {
        type: String,
    },
    tranferRefCode: {
        type: String,
    },
    amount: {
        type: String,
    },
    username: {
        type: String
    },
    avatar: {
        type: String
    },
    date: {
        type: Date,
        default: Date.now
    }
})

module.exports = Wallet = mongoose.model('wallet', walletSchema)

Result of payment add

{
    "newPayment": {
        "_id": "5ec0a61597d09440249a1dcc",
        "bankName": "sbi",
        "tranferRefCode": "kfjalskdfjkasdfjajs",
        "amount": "1000",

        "date": "2020-05-17T02:48:53.662Z",
        "__v": 0
    }
}

This is 100% worked

 router.get('/myPayment/user', auth, async (req, res) => {
        UserWallet.find({ paymentBy: req.user.id })
            .populate("paymentBy", "_id username email")
            .then(myPanment => {
                res.json({myPanment})
            })
            .catch(err => {
                console.log(err);
                res.json({msg: err})            
            })
    });
