Laravel Echo 未订阅 Pusher Presence Channel，甚至在 Pusher 仪表板中也不订阅

如何解决Laravel Echo 未订阅 Pusher Presence Channel，甚至在 Pusher 仪表板中也不订阅

我花了很多时间来解决我的这个问题，多次阅读文档，到处谷歌搜索：SO、Laracast、Larachat 等，但仍然无法让 Laravel Echo 订阅 Pusher 在线频道，并且它在控制台选项卡中没有显示任何错误

公共和私人频道运行良好且流畅，用户可以订阅，用户可以收听/触发事件

注意：在创建这篇文章之前，我有与我当前问题相关的搜索问题，他们都没有答案

一些和我类似的问题：

规格：

Laravel：7.30.1
laravel-Echo: 1.10.0 (latest; atm)
pusher/pusher-php-server：4.0
pusher-js: 7.0.3 (latest; atm)

在resource/js/bootstrap.js

import Echo from 'laravel-echo'

window.Pusher = require('pusher-js');

window.Echo = new Echo({
    broadcaster: 'pusher',key: process.env.MIX_PUSHER_APP_KEY,cluster: process.env.MIX_PUSHER_APP_CLUSTER,forceTLS: true,authEndpoint: '/api/broadcasting/auth',auth: {
        headers: {
            'Authorization': `Bearer ${localStorage['token']}`
        }
    }    
});

在routes/api.php

// https://stackoverflow.com/questions/55555844/authorizing-broadcasting-channel-in-an-spa
Route::post('/broadcasting/auth',function (Request $request) {
    $pusher = new Pusher\Pusher(
        env('PUSHER_APP_KEY'),env('PUSHER_APP_SECRET'),env('PUSHER_APP_ID'),[
            'cluster' => env('PUSHER_APP_CLUSTER')
        ]
    );

    // This will return JSON response: {auth:"__KEY__"},see comment below
    // https://pusher.com/docs/channels/server_api/authenticating-users
    $response = $pusher->socket_auth($request->request->get('channel_name'),$request->request->get('socket_id'));

    return $response;
})->middleware('auth:sanctum');

在routes/channels.php

// https://laravel.com/docs/8.x/broadcasting#authorizing-presence-channels
Broadcast::channel('whatever',function ($user) {
    return [
        'id' => $user->id,'name' => $user->name
    ];
});

在home.vue

...
...
created() {
    Echo.join('whatever') // DOES NOT WORK,Even in mounted() vue lifehook,and in Pusher dashboard,it doesn't show this channel name
        .here((users) => {
            console.table(users)
        })
}

问：为什么 Laravel Echo 不订阅 Pusher 在线频道？甚至在 Pusher 中，它也没有显示频道名称：presence-whatever，只有 disconnected（在我刷新页面后）然后 connected 就像 没有发生
