Laravel Artisan event:generate command throwing a Fatal error - php

Question

I'm following the official documentation for Laravel 5.7 on the events registration and generation: https://laravel.com/docs/5.7/events#generating-events-and-listeners
I have an EventServiceProvider with the following events defined:
<?php
namespace App\Providers;
use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;
class EventServiceProvider extends ServiceProvider
{
/**
* The event handler mappings for the application.
*
* #var array
*/
protected $listen = [
'App\Events\FormBeforeCreate' => [
'App\Listeners\WebhookBeforeCreate',
],
'App\Events\FormAfterCreate' => [
'App\Listeners\NotifyAfterCreate',
'App\Listeners\WebhookAfterCreate',
],
'App\Events\FormBeforeUpdate' => [
'App\Listeners\WebhookBeforeUpdate',
],
'App\Events\FormAfterUpdate' => [
'App\Listeners\NotifyAfterUpdate',
'App\Listeners\WebhookAfterUpdate',
],
'App\Events\FormBeforeDelete' => [
'App\Listeners\WebhookBeforeDelete',
],
'App\Events\FormAfterDelete' => [
'App\Listeners\NotifyAfterDelete',
'App\Listeners\WebhookAfterDelete',
],
'App\Events\FormBeforeSave' => [
'App\Listeners\WebhookBeforeSave',
],
'App\Events\FormAfterSave' => [
'App\Listeners\NotifyAfterSave',
'App\Listeners\WebhookAfterSave',
],
];
/**
* The subscriber classes to register.
*
* #var array
*/
protected $subscribe = [
'App\Listeners\UserEventSubscriber',
];
/**
* Register any other events for your application.
*
* #return void
*/
public function boot()
{
parent::boot();
}
}
The error:
When I run the command php artisan event:generate I get the following error:
PHP Fatal error: Call to a member function listens() on null in /app/vendor/laravel/framework/src/Illuminate/Foundation/Console/EventGenerateCommand.php on line 35
[Symfony\Component\Debug\Exception\FatalErrorException]
Call to a member function listens() on null
According to the doc, it should do this:
This command will generate any events or listeners that are listed in
your EventServiceProvider. Events and listeners that already exist
will be left untouched
I don't understant what I've missed since I didn't find any similar error by searching the web

This is the line that is returning null:
$providers = $this->laravel->getProviders(EventServiceProvider::class);
therefore, there are some problems with your EventServiceProvider... please, try using this:
<?php
namespace App\Providers;
use Illuminate\Support\Facades\Event;
use Illuminate\Auth\Events\Registered;
use Illuminate\Auth\Listeners\SendEmailVerificationNotification;
use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;
class EventServiceProvider extends ServiceProvider
{
/**
* The event listener mappings for the application.
*
* #var array
*/
protected $listen = [
'App\Events\FormBeforeCreate' => [
'App\Listeners\WebhookBeforeCreate',
],
'App\Events\FormAfterCreate' => [
'App\Listeners\NotifyAfterCreate',
'App\Listeners\WebhookAfterCreate',
],
'App\Events\FormBeforeUpdate' => [
'App\Listeners\WebhookBeforeUpdate',
],
'App\Events\FormAfterUpdate' => [
'App\Listeners\NotifyAfterUpdate',
'App\Listeners\WebhookAfterUpdate',
],
'App\Events\FormBeforeDelete' => [
'App\Listeners\WebhookBeforeDelete',
],
'App\Events\FormAfterDelete' => [
'App\Listeners\NotifyAfterDelete',
'App\Listeners\WebhookAfterDelete',
],
'App\Events\FormBeforeSave' => [
'App\Listeners\WebhookBeforeSave',
],
'App\Events\FormAfterSave' => [
'App\Listeners\NotifyAfterSave',
'App\Listeners\WebhookAfterSave',
],
];
/**
* Register any events for your application.
*
* #return void
*/
public function boot()
{
parent::boot();
//
}
}

My bad, it seems like I was really tired yesterday night, Our project runs on Docker, I was running the command outside of the docker instead of inside.
I have no idea why it showed this bug in particular but once I ran the command in the docker all files generated correctly.
