你好我们正试图在laravel发送一封电子邮件，事情是它给我这个错误。有人可以解释为什么我面临这个错误。这是我的代码：
Route::get('testmail', function () {
/* \Mail::send('emails.test', array(), function ($m) {
$m->from('contrivesol@gmail.com', 's2c Mobile');
$m->subject('Review Request For ');
$m->to("gardezisyedmuhammadali@gmail.com", "Gardezi");
});
*/
$user='';
\Mail::send('emails.test', ['user' => null], function ($m) use ($user) {
$m->from('contrivesol@gmail.com', 'Your Application');
$m->to('ovaiz.mushtaq@gmail.com', 'Awais')->subject('Your Reminder!');
});
});
以下是我的错误日志
