我正在尝试从数据库中删除几个项目（mongoose）通过选择它们并单击删除按钮。我已经设法从数据库中获取列表中每个元素的ID。我正在收集列表中所选项目的ID并将其存储在名为isCHecked的数组中，但问题是当我单击立即删除它们时，我得到一个AxiosError {message: 'Request failed with status code 400', name: 'AxiosError', code: 'ERR_BAD_REQUEST'错误。我觉得ID没有有效地传递到后端，请问我哪里弄错了？
这里只是代码片段。谢谢

const StockItems = () => {
    const [stockItemsList, setStockItemsList] = useState([])
    const [showCheckBox, setShowCheckBox] = useState(false)
    const [isCHecked, setIsChecked] = useState([])

    const handlecheckbox=(e)=>{
        const {value, checked} = e.target
        console.log(value)
        if(checked){
           setIsChecked([...isCHecked, value])
        }else
          setIsChecked(isCHecked.filter((e)=> e!==value))

    }

    const deleteAll = async()=>{
        console.log(isCHecked)
         await Axios.delete('http://localhost:3500/newItems', {isCHecked}).then((response) => {
            console.log(response.status)
            console.log(response.data)
        })
        .catch((e) => console.log('something went wrong :(', e));
        //setDeleteMessage(response.data.deleteMessage)
    }
}

//controller code (Backend)
const NewItemsData = require('../models/NewItemsData')
const asyncHandler = require('express-async-handler')

const deleteNewItems = asyncHandler(async (req, res) => { 
    const id = req.body
    console.log(id) // this shows undefined in the console

    if(!id) {
       return res.status(400).json({message: 'Items Id is required'})
    }
    const items = await NewItemsData.findById({_id: {$in: id}}).exec()

    if(!items){
       return res.status(400).json({message: 'Items does not exist'})
    }

     await items.deleteMany()
   // const reply = `Username ${result.username} with ID ${result._id} deleted`
    res.json({message: 'Items has been deleted'})
})

module.exports = {
    deleteNewItems,  
}

//Server
app.use('/newItems', require('./routes/newItemsRoutes'))// a line just to show how my route is mounted in the server

//Routes
const express = require('express')
const router = express.Router()
const newItemsController = require('../contollers/newItemsController')

router.route('/')
      .get(newItemsController.getAllNewItems)
      .post(newItemsController.createNewItems)
      .patch(newItemsController.updateNewItems)
      .delete(newItemsController.deleteNewItems)
