我想更新用户数据。我成功获取现有用户数据，但没有更新。显示以上错误。 当我从下面一行删除一个等号时，错误将被删除，但用户数据仍然没有更新。

const existingUser = users.userList.filter(f => f.id == id);

import React, { useState } from 'react'
import { useSelector, useDispatch } from 'react-redux';
import { useNavigate, useParams } from 'react-router-dom';
import { updateUser } from '../redux/slice/userReducer';

const Update = () => {
  const { id } = useParams();
  //console.log(id)

  const users = useSelector((state) => state.users);
  const existingUser = users.userList.filter(f => f.id === id);
  //console.log(existingUser);

  const { name, email } = existingUser[0];
  const [uname, setName] = useState(name);
  const [uemail, setEmail] = useState(email);

  const dispatch = useDispatch();
  const navigate = useNavigate();

  const handleUpdate = (event) => {
    event.preventDefault();
    dispatch(updateUser({
      id: id,
      name: name,
      email: email
    }));
    navigate('/');
  }

  return (
    

      

        
Update User
        

          

            Name:
             setName(e.target.value)}
            />
          
          

            Email:
             setEmail(e.target.value)}
            />
          
          

          Update
        
      
    
  )
}

export default Update
