遇到问题

问题描述：在启动时无法投递一个异步任务到task_worker池中，导致聊天室无法加载用户相关信息
官方文档：https://wiki.swoole.com/wiki/page/134.html

环境配置：
swoole version 4.2.13
php version 7.2.14
easy swoole 3.1.14

namespace EasySwoole\EasySwoole\Swoole\Task;
class TaskManager
{
    public static function async($task,$finishCallback = null,$taskWorkerId = -1)
    {
        /* 测试代码
        $task_id = ServerManager::getInstance()->getSwooleServer()->task($task,-1, function (\swoole_server $serv, $task_id, $data) {
            echo "Task Callback: ";
            var_dump($task_id, $data);
        });
        var_dump($task_id);*/
        //修复：针对回调函数判断即可
        $finishCallback =  is_null($finishCallback) ? function (\swoole_server $serv, $task_id, $data){} : $finishCallback;
        return ServerManager::getInstance()->getSwooleServer()->task($task,$taskWorkerId,$finishCallback);
    }
