Hi, i'm currently trying to implement your library to my project.
I'm use PostgreSQL as my database connection and got this error message

PHP Notice 'yii\base\ErrorException' with message 'unserialize(): Error at offset 112 of 116 bytes'

in /Users/samdgea/Documents/Workspace/Yii2/sipk-yii2/vendor/bazilio/yii2-async/transports/AsyncMysqlTransport.php:88

Here's the stack trace

Here's my code
private function _sendVerificationEmail($user, $subject = "Please validate your account")
{
$message = Yii::$app->mailer->compose()
->setFrom('[email protected]')
->setTo($user->email_address)
->setSubject($subject)
->setTextBody("Hi, this is your verification code: " . $user->email_verification_hash . "\nPlease ignore if you did not request it");
return Yii::$app->mailer->send($message);
}

and this is my configuration file
$config = [
....
'mailer' => [
'class' => \YarCode\Yii2\AsyncMailer\Mailer::class,
'syncMailer' => [
'class' => yii\swiftmailer\Mailer::class,
'useFileTransport' => true,
'transport' => [
'class' => 'Swift_SmtpTransport',
'host' => 'smtp.mailtrap.io',
'username' => 'xx',
'password' => '9xx',
'port' => '2525',
'encryption' => 'tls',
],
],
],
...
];

Hi, i'm currently trying to implement your library to my project.
Can i ask question, why in MailerCommand class need to execute SELECT 1 from $app->db?
Actually my app has no database connection, except redis connection that this library needed.

Thanks
