laravel的octane在启动时，相关`request`回调函数的疑问？

1. 运行环境

docker / linux
Linux: alpine3.15.0

1). 当前使用的 Laravel 版本？

"name": "laravel/framework",
"version": "v8.81.0", 

2). 当前使用的 php/php-fpm 版本？

PHP 版本：8.1

3). 当前系统

Linux: alpine3.15.0

4). 业务环境

5). 相关软件版本

"laravel/octane": "^1.2"

2. 问题描述？

以下代码$server->on('request'.....)闭包函数的$workerState参数继承自父作用域，可父作用域中没有设置workerState->worker , 那么函数体内怎么可以调用workerState->worker。

require_once __DIR__.'/WorkerState.php';

$workerState = new WorkerState;

$workerState->cacheTable = require __DIR__.'/createSwooleCacheTable.php';

$workerState->timerTable = $timerTable;

$workerState->tables = require __DIR__.'/createSwooleTables.php';

$server->on('workerstart', fn (Server $server, $workerId) =>

    (fn ($basePath) => (new OnWorkerStart(

        new SwooleExtension, $basePath, $serverState, $workerState

    ))($server, $workerId))($bootstrap($serverState))

);

$server->on('request', function ($request, $response) use ($server, $workerState, $serverState) {

$workerState->lastRequestTime = microtime(true);

if ($workerState->timerTable) {

    $workerState->timerTable->set($workerState->workerId, [

        'worker_pid' => $workerState->workerPid,

        'time' => time(),

    ]);

}

$workerState->worker->handle(...$workerState->client->marshalRequest(new RequestContext([

    'swooleRequest' => $request,

    'swooleResponse' => $response,

    'publicPath' => $serverState['publicPath'],

    'octaneConfig' => $serverState['octaneConfig'],

])));

if ($workerState->timerTable) {

    $workerState->timerTable->del($workerState->workerId);

}

});

3. 您期望得到的结果？

以上代码`$server->on('request'.....)`闭包函数的$workerState参数继承自父作用域，可父作用域中没有设置workerState->worker ,  那么函数体内怎么可以调用workerState->worker。

4. 您实际得到的结果？
