Php 未经认证的Laravel推进器

这就是我的活动

$post = Post::create([
            'title' => $request->title,
            'body' => $request->body,
            'user_id' => auth()->id(),
        ]);
event(new PostPublished($post));

此方法的路径是

Auth::routes();
Route::post('posts', [App\Http\Controllers\HomeController::class, 'storePost'])->name('posts.store');

在我的活动中，我就是这样调用

broadcastOn（）

public function broadcastOn()
{
    return new Channel('post');
}

在我的

channels.php

Broadcast::channel('post', function () {
    return true;
}, ['guards' => ['web']]);

现在我在我的组件中做这个

Echo.channel(`post`).listen("PostPublished", (post) => {
                Notification.requestPermission((permission) => {
                    let notification = new Notification("Congrats on new Post", {
                        body: post.title,
                        icon: "https://pusher.com/static_logos/320x320.png",
                    });

                    notification.onclick = () => {
                        window.open(window.location.href);
                    };
                });
            });

但是它给我带来了错误

它带来了什么样的错误？
