我遇到此错误

但检查 Postman 它告诉我，一切都很好，但当我检查数据库，我没有看到任何工作正常。
我的端点应该把钱从一个钱包发送到另一个钱包（虚拟的），但这似乎不起作用，不知道为什么。

https://*********.onrender.com/api/wallet/wallet-transfer?email=**@yopmail.com&email=**@gmail.com&amount=16800

我的代码

const router = require("express").Router();
const User = require("../models/User");
const Trans = require("../models/Transactions");
const bcrypt = require("bcrypt");
const jwt = require("jsonwebtoken");

router.get("/wallet-transfer", async (req, res) => {

    try {
        if (
          !req.headers.authorization ||
          !req.headers.authorization.startsWith("Bearer ") ||
          !req.headers.authorization.split(" ")[1]
        ) {
          return res.status(422).json({ message: "Please Provide Token!" });
        }

        const amount = parseInt(req.query.amount);

        //Debit user
        const debit = await User.find({ email: req.query.email });
        const debit_balance = parseInt(debit[0].balance);
        const debit_amt = debit_balance - amount;

        //credit User
        const credit = await User.find({ email: req.query.email });
        const credit_balance = parseInt(credit[0].balance);
        const credit_amt = credit_balance + amount;

        //set Debit account with updated amount
        try{
          await User.findOneAndUpdate({email : req.query.email}, {$set: {balance: debit_amt}});
          const transactions = new Trans({
            email: req.query.email,
            narration: 'DEBIT - '+debit_amt,
            credit: 0.00,
            debit: debit_amt,
            amount: debit_amt,
          });
          transactions.save();

          //set credit  account with updated amount
          await User.findOneAndUpdate({email : req.query.email}, {$set: {balance: credit_amt}});
          const trx = new Trans({
            email: req.query.email,
            narration: 'CREDIT - '+credit_amt,
            credit: credit_amt,
            debit: 0.00,
            amount: credit_amt,
          });
          trx.save();

        }catch(err){
          console.log(err);
        }

        return res.send({ error: false, message: "Wallet Transfer Complete" });

      } catch (error) {
        res.status(404).json({ message: error.message });
      }

});

module.exports = router;

如何解决呢？
