其实在我的导航栏我想显示登录和注销的时间。当它显示注销，如果用户点击，那么它应该相应地工作。但它不能正常工作。相反，它显示错误。isAuthenticated在reducer.js中可用

Navbar.jsx:

import React, { useState } from "react";
import { NavLink, useNavigate } from "react-router-dom";
import { useSelector, useDispatch } from "react-redux";
import { logout } from "../../redux/actions";
import { links } from "../../data";
import "./Navbar.css";

const Navbar = () => {
  const [showMenu, setShowMenu] = useState(false);
  const isAuthenticated = useSelector((state) => state.auth.isAuthenticated);
  const dispatch = useDispatch();
  const navigate = useNavigate();

  const toggleMenu = () => {
    setShowMenu(!showMenu);
  };

  const handleLogout = () => {
    dispatch(logout());
    navigate("/");
  };

  let filteredLinks = links;

  if (isAuthenticated) {
    filteredLinks = links.filter((link) => link.name !== "Login");
  } else {
    filteredLinks = links.filter((link) => link.name !== "Logout");
  }

  return (
    <nav className="nav">
      <div className={`${showMenu ? "nav_menu show-menu" : "nav_menu"}`}>
        <ul className="nav_list">
          {filteredLinks.map(({ id, name, icon, path }) => (
            <li className="nav_item" key={id}>
              {name === "Logout" ? (
                <a className="nav_link" onClick={handleLogout}>
                  {icon}
                  <h3 className="nav_name">{name}</h3>
                </a>
              ) : (
                <NavLink
                  to={path}
                  className={({ isActive }) =>
                    isActive ? "nav_link active-nav" : "nav_link"
                  }
                  onClick={toggleMenu}
                >
                  {icon}
                  <h3 className="nav_name">{name}</h3>
                </NavLink>
              )}
            </li>
          ))}
        </ul>
      </div>

      <div
        className={`${showMenu ? "nav_toggle animate-toggle" : "nav_toggle"}`}
        onClick={toggleMenu}
      >
        <span></span>
        <span></span>
        <span></span>

我想要一个能帮助我解决这个问题的方法。如果有人能帮助我摆脱这个问题，那将是非常有帮助的。先谢谢你了
