Laravel 5.5 Queues & Jobs : job is never executed - laravel

Question

I'm fairly new to Lumen (Laravel), and I'm currently digging the concept of Queues, Jobs & Scheduled Tasks.
I would like to store in a Queue some Eloquent models, when I receive them from API calls. Then, I want to create a scheduled task which runs a daily Job, to fetch all those models in Queue and then send a report email.
I went the database storing way for Queues.
So I added the QUEUE_DRIVER=database key in my .env file and my queue.php config file looks like this :
<?php
return [
'database' => [
'connection' => 'my_db_connection',
'driver' => 'database',
'table' => 'jobs',
'queue' => 'default',
'retry_after' => 90
]
];
I ran the php artisan queue:table command to create the migration file and ran migration to create my table. I have a table jobs, with the right intended fields.
I created a class, implementing ShouldQueue :
class ProcessDeliveryOrders implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
protected $deliveryOrder;
public function __construct($deliveryOrder)
{
$this->deliveryOrder = $deliveryOrder;
}
public function handle()
{
// $this->deliveryOrder->save(); ?
}
}
As sub-question here is about how this class is working : Can it stores automatically the Eloquent model when it receives it in it's constructor ? to me the handle method is called when the object is retrieved by the Job, but I can be wrong and it's used to store the object ?
Then, I created a MailingJob : it's goal is to aggregate all the ProcessDeliveryOrders stored daily, and create an email from them :
class SendDeliveryEmailJob extends Job
{
public function __construct()
{
//
}
public function handle()
{
// DeliveryOrder is my Eloquent Model
$deliveryOrders = DeliveryOrder::query()
->whereBetween('createdAt', [strtotime('today midnight'), strtotime('today midnight')])
->get();
$mail = Mail::to(config('admin.emails'));
$mail->send(
new DeliveryOrderReportMailTemplate([
'deliveryOrders' => $deliveryOrders
])
);
}
}
And in my Kernel.php, I have added the following line in function schedule() :
// everyMinute for test purposes only
$schedule->job(new SendDeliveryEmailJob())->everyMinute();
As I'm using Lumen, I don't have the exact same process as in pure Laravel, so when I receive a delivery order to call my dispatch, I tried both ways exposed by the Lumen doc (forced to create an instance of my Job) :
dispatch(new ProcessDeliveryOrders($deliveryOrder));
// OR
Queue::push(new ProcessDeliveryOrders($deliveryOrder));
After all this setup, I tried few commands like php artisan queue:listen or php artisan queue:work, and the command line seems to be stuck.
If I run php artisan queue:listen database I get the following looped error :
In QueueManager.php line 172:
No connector for []
I checked documentation twice, and tried the new key QUEUE_CONNECTION=database instead of QUEUE_DRIVER but it's apparently only since 5.7, and didn't worked either. Any chance you spot something I'm missing ? Thanks a lot
EDIT: When I put a logging in the SendDeliveryEmailJob constructor, and I run php artisan queue:listen, I see the echo output every 2 or 3 seconds. I've also put a log into the handle function but I never see this one called.
EDIT 2: I noticed that when I try to execute my scheduled tasks with php artisan scheduled:run, it throws an error :
Running scheduled command: App\Jobs\SendDeliveryEmailJob
In Schedule.php line 87:
Call to a member function onQueue() on null
I guess from this message, that my Job is not instanciated, but I see the constructor message displayed to it's kinda weird..

#alex QUEUE_CONNECTION=database put this in your env and your queue.php is
'sync' => [
'driver' => 'sync',
],
'database' => [
'driver' => 'database',
'table' => 'jobs',
'queue' => 'default',
'retry_after' => 90,
],
