This is more PHP language question. You don't call parent constructor. I would not recommend extend the constructor.

I recommend using an Action class instead: https://docs.espocrm.com/development/api-action/#action

I'm struggling with some weird error once I go to my custom entity via de browser: ERROR: Slim Application Error Type: Error Code: 0 Message: Typed property Espo\Core\Controllers\RecordBase::$searchParamsFet cher must not be accessed before initialization.

I have created a custom controller via the entity manager and added the following code:

<?php
namespace Espo\Custom\Controllers;
use Espo\Custom\Services\EmptyService;
class CallbackEntity extends \Espo\Core\Templates\Controllers\Base
{
    public function __construct(private EmptyService $emptyService)
    { }
}​

The code of my service is:

<?php
namespace Espo\Custom\Services;
class EmptyService
{
    public function getEmptyValue(): string
    {
        return "empty value";
    }
}​

If i comment the __contruct it's all working. What is going wrong here?
