react，如何实现删除指定项？

在使用的react版本如下：

import { AddCircleOutline, CloseCircleOutline } from 'antd-mobile-icons'
function Rent() {
    const [list, setList] = useState([])
    API.get('/user/houses').then(res=>{
    const { status, body } = res.data
    setList(body)})
    const deleteRent = (e) => {
      let index = e.target.getAttribute("data-index")
      list.splice(index, 1, "")
      setList(list)
    }
    const renderHouseItem = () => {
      return list.map(item => {
        return (
          <div className={styles.A} key={item.houseCode}>
            <div>
              <HouseItem
                // key={item.houseCode}
                onClick={() => navigate(`/detail/${item.houseCode}`)}
                src={BASE_URL + item.houseImg}
                title={item.title}
                desc={item.desc}
                tags={item.tags}
                price={item.price}
                style={{'height': '105px'}}
              />
            </div>
            <span className={styles.delete} key={item.index} data-index={item.index} onClick={(e)=>{e.stopPropagation();deleteRent()}}><CloseCircleOutline /></span>
          </div>
        )
      })
    }
  const renderRentList = () => {
    return <div className={styles.houses}>{renderHouseItem()}</div>
  }
  return (<>
      <div className={styles.root}>
        {renderRentList()}
      </div>
      </>
  )
}

目前效果如下，删除按钮可成功显示出来，然而，点击删除图标后，浏览器显示target未定义：

请问以上代码写得有哪些不对的地方吗？请展示代码举例说明，谢谢。

import { AddCircleOutline, CloseCircleOutline } from 'antd-mobile-icons'
function Rent() {
    const [list, setList] = useState([])
    API.get('/user/houses').then(res=>{
    const { status, body } = res.data
    setList(body)})
    const deleteRent = (index) => {
      list.splice(index, 1, "")
      setList(list)
    }
    const renderHouseItem = () => {
      return list.map(item => {
        return (
          <div className={styles.A} key={item.houseCode}>
            <div>
              <HouseItem
                // key={item.houseCode}
                onClick={() => navigate(`/detail/${item.houseCode}`)}
                src={BASE_URL + item.houseImg}
                title={item.title}
                desc={item.desc}
                tags={item.tags}
                price={item.price}
                style={{'height': '105px'}}
              />
            </div>
            <span className={styles.delete} key={item.index} data-index={item.index} onClick={(e)=>{e.stopPropagation();deleteRent(item.index)}}><CloseCircleOutline /></span>
          </div>
        )
      })
    }
  const renderRentList = () => {
    return <div className={styles.houses}>{renderHouseItem()}</div>
  }
  return (<>
      <div className={styles.root}>
        {renderRentList()}
      </div>
      </>
