这是代码：出现错误， 'ReferenceError: Cannot access 'parsePayload' before initialization' 请帮忙

const express = require("express");
const { createToDo, updateToDo } = require("./types");
const { todo } = require("./db");


const app = express();

app.use(express.json());

app.post('/to-do',async function(req,res){

    const createPayload = req.body;
    const parsePayload = createToDo.safeParse(parsePayload);

    if(!parsePayload.success){

        res.status(411).json({

            "msg" : "you sent the wrong input"

        })

        return;
    }

    await todo.create({
        title : createPayload.title,
        description : createPayload.description,
        completed : false
    })

    res.json({
        "msg" : "To Do Created"
    })

})

app.get('/to-do',async function(req,res){

       const todos = await todo.find();
       console.log(todos);

       res.json({
        todos
       })


})

app.put('/to-do',async function(req,res){

    const updatePayload = req.body;
    const parsePayload = updateToDo.safeParse(parsePayload);

    if(!parsePayload.success){

        res.status(411).json({

            "msg" : "you send the wrong id or input"

        })

        return;


    }

    await todo.update({
        _id : req.body.id
    },{
        completed : true
    })

    res.json({
        "msg" : "todo marked updated"
    })

})

app.listen(3000);
