Getting the error InvalidArgumentException Unable to resolve NULL driver for [Illuminate\Mail\TransportManager] on Lumen using smtp driver. I followed all the steps setting up Mail in the lumen documentation. Here is my env
MAIL_DRIVER=smtp
MAIL_HOST=domain.com
MAIL_PORT=465
MAIL_USERNAME=username@domain.com
MAIL_PASSWORD=password
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS=no-reply@username@domain.com
MAIL_FROM_NAME="Company name"
Added the mail.php from the laravel repo into the lumen.../config folder
<?php

added the following to my app.php in bootstrap
$app->register(Illuminate\Mail\MailServiceProvider::class);
$app->configure('mail');
$app->configure('services');
$app->alias('mailer', Illuminate\Mail\Mailer::class);
$app->alias('mailer', Illuminate\Contracts\Mail\Mailer::class);
$app->alias('mailer', Illuminate\Contracts\Mail\MailQueue::class);
The implementation making sending the email
public function testMail()
{
Mail::to('username2@domain.com.com')->send(new MailableClass('George','Kindly note that your email has been sent'));
}
MailableClass simply being a class that extends Mailable to build the view
i also did a data dump of the config('mail') which returned this
array:4 [▼
"default" => "smtp"
"mailers" => array:7 [▼
"smtp" => array:8 [▼
"transport" => "smtp"
"host" => "username@domain.com"
"port" => "465"
"encryption" => "tls"
"username" => "username@domain.com"
"password" => "password"
"timeout" => null
"auth_mode" => null
]
"ses" => array:1 [▶]
"mailgun" => array:1 [▶]
"postmark" => array:1 [▶]
"sendmail" => array:2 [▶]
"log" => array:2 [▶]
"array" => array:1 [▶]
]
"from" => array:2 [▶]
"markdown" => array:2 [▶]
i check the Manager.php and TransportManager.php files in illuminate/mail when i set the driver value of the driver function to "smtp" I able to pass to the createSmtpDriver() of TransportManager.php. You can see the respective codes here...
/**
* Get a driver instance.
*
* @param string $driver
* @return mixed
*
* @throws \InvalidArgumentException
*/
public function driver($driver = "smtp") //originally $driver = null
{
$driver = $driver ?: $this->getDefaultDriver();
if (is_null($driver)) {
throw new InvalidArgumentException(sprintf(
'Unable to resolve NULL driver for [%s].', static::class
));
}
// If the given driver has not been created before, we will create the instances
// here and cache it so we can return it next time very quickly. If there is
// already a driver created by this name, we'll just return that instance.
if (! isset($this->drivers[$driver])) {
$this->drivers[$driver] = $this->createDriver($driver);
}
return $this->drivers[$driver];
}
I did a dd in the createSmtpDriver()
protected function createSmtpDriver()
{
$config = $this->app->make('config')->get('mail');
**dd($config);**
// The Swift SMTP transport instance will allow us to use any SMTP backend
// for delivering mail such as Sendgrid, Amazon SES, or a custom server
// a developer has available. We will just pass this configured host.
$transport = new SmtpTransport($config['host'], $config['port']);
if (isset($config['encryption'])) {
$transport->setEncryption($config['encryption']);
}
// Once we have the transport we will check for the presence of a username
// and password. If we have it we will set the credentials on the Swift
// transporter instance so that we'll properly authenticate delivery.
if (isset($config['username'])) {
$transport->setUsername($config['username']);
$transport->setPassword($config['password']);
}
// Next we will set any stream context options specified for the transport
// and then return it. The option is not required any may not be inside
// the configuration array at all so we'll verify that before adding.
if (isset($config['stream'])) {
$transport->setStreamOptions($config['stream']);
}
return $transport;
}
the results of this dd was basically the results in config('mail') above and from that we can see the config['host'], config['port'] ..etc will return nothing because they are in mailer so i thinking it should be config['mailer']['host'] instead... but these are all framework files so...
I will really appreciate the assistance figuring this out.. at a total loss what I am doing wrong. Thank you
oh right forgot I have also installed..
composer require guzzlehttp/guzzle
Thank you
