Fix #1379

Should the phpstan-baseline.neon file be regenerated with the new errors?

Should the phpstan-baseline.neon file be regenerated with the new errors?

I regenerated it, but nothing has changed with these new modifications

Sorry ;).

I think it should be added to the phpstan.neon.dist file:

parameters:
    doctrine:
        objectManagerLoader: tests/object-manager.php

And a new file tests/object-manager.php

<?php

use App\Kernel;
use Symfony\Component\Dotenv\Dotenv;

require __DIR__.'/../vendor/autoload.php';

(new Dotenv())->bootEnv(__DIR__.'/../.env');

$kernel = new Kernel($_SERVER['APP_ENV'], (bool) $_SERVER['APP_DEBUG']);
$kernel->boot();

return $kernel->getContainer()->get('doctrine')->getManager();
