我想创建一个日志来通知新用户的注册，问题出在行中，我想创建一个日志来通知新用户的注册，问题出在$log_message = Log::channel('logRegisterUser')->info("{$name_user} registered using the IP {$ip_user} in {$data}.");行中，当放置在dd()中时显示为null。在'description_log' => $log_message,行中创建此错误。

• logging.php

'logRegisterUser' => [
            'driver' => 'single',
            'path' => storage_path('logs/logRegisterUser.log'),
            'level' => 'debug',
        ],

• RegisteredUserController.php

public function __construct()
    {
        $this->logModel = new LoggingModel();
    }
    
    public function create()
    {
        return view('auth.register');

            'password' => ['required', 'confirmed', Rules\Password::defaults()],
        ]);

        $user = User::create([

        ]);

        event(new Registered($user));

        $date = Carbon::now()->format('d/m/Y H:i:s');
        $name_user = $user->name;
        $ip_user = request()->ip();
        $log_message = Log::channel('logRegisterUser')->info("{$name_user} registered using the IP {$ip_user} in {$data}.");
