I’m trying to use [initializers](https://docs.laminas.dev/laminas-servicemanager/configuring-the-service-manager/#initializers) in my service manager config in `module.config.php`. This is my config:

```auto
<?php

/**
 * @see https://github.com/laminas/laminas-mvc-skeleton for the canonical source repository
 *
 * @copyright https://github.com/laminas/laminas-mvc-skeleton/blob/master/COPYRIGHT.md
 * @license https://github.com/laminas/laminas-mvc-skeleton/blob/master/LICENSE.md New BSD License
 */

declare(strict_types=1);

namespace Worker;

use Laminas\ServiceManager\Factory\InvokableFactory;
use Worker\Command\HelloCommand;
use Worker\Command\PublishCommand;
use Worker\Command\QueueCommandInitializer;
use Worker\Service\ElasticService;
use Worker\Service\ElasticServiceFactory;
use Worker\Service\RabbitmqService;
use Worker\Service\RabbitmqServiceFactory;

return [
    'laminas-cli' => [
        'commands' => [
            'app:hello' => HelloCommand::class,
            'app:publish' => PublishCommand::class,
        ],
    ],
    'service_manager' => [
        'factories' => [
            HelloCommand::class => InvokableFactory::class,
            PublishCommand::class => InvokableFactory::class,
            RabbitmqService::class => RabbitmqServiceFactory::class,
            ElasticService::class => ElasticServiceFactory::class
        ],
        'initializers' => [
            new QueueCommandInitializer()
        ]
    ],
];

```

The QueueCommandInitializer looks like this:

```auto
<?php

/**
 * @see https://github.com/laminas/laminas-mvc-skeleton for the canonical source repository
 *
 * @copyright https://github.com/laminas/laminas-mvc-skeleton/blob/master/COPYRIGHT.md
 * @license https://github.com/laminas/laminas-mvc-skeleton/blob/master/LICENSE.md New BSD License
 */

declare(strict_types=1);

namespace Worker\Command;

use Laminas\ServiceManager\Initializer\InitializerInterface;
use Psr\Container\ContainerInterface;
use Worker\Service\RabbitmqService;

class QueueCommandInitializer implements InitializerInterface
{
    public function __invoke(ContainerInterface $container, HelloCommand $instance)
    {
        if (!$instance instanceof QueueCommandInterface) {
            return;
        }
        $instance->setQueue($container->get(RabbitmqService::class));
    }
}

```

The `QueueCommandInterface` is an empty interface.

When I try to run my app I get the following error:

```auto
Fatal error: Uncaught Error: Class "Worker\Command\QueueCommandInitializer" not found in /Users/<redacted>/module/Worker/config/module.config.php:38

```

And I can’t figure out why. Any ideas?

Use the delegators instead: [Migration Guide - laminas-servicemanager - Laminas Docs](https://docs.laminas.dev/laminas-servicemanager/migration/#initializers)

The class name and the namespace looks good, please check the filename.

Filename looks good, too I think: `module/Worker/src/Command/QueueCommandInitializer.php`

The class `QueueCommandInitializer` is not compatible with the interface of `Laminas\ServiceManager\Initializer\InitializerInterface`:

> [@matti](#):
>
> ```auto
> public function __invoke(ContainerInterface $container, HelloCommand $instance);
>

It must be:

```auto
public function __invoke(ContainerInterface $container, $instance);

```

Apart from that, everything works for me.

Thanks! How would I hint my IDE so it knows what methods are available on that instance, though? A DocBlock…?

EDIT: Ah. You mention the methods in the interface.

```auto
<?php

declare(strict_types=1);

namespace Worker\Command;

use Worker\Service\RabbitmqService;

interface QueueCommandInterface
{
    public function setQueue(RabbitmqService $queue): void;
}

```
