I am getting the following error on di compile:

Extra parameters passed to parent construct $directoryHelper

Thats the original code:

class PreviewButton extends \Magento\Config\Block\System\Config\Form\Field {

protected $blockFactory; public function __construct( \Magento\Backend\Block\Template\Context $context, \Magento\Framework\View\Element\BlockFactory $blockFactory, array $data = [], ?SecureHtmlRenderer $jsonHelper = null, ?DirectoryHelper $directoryHelper = null ) { $this->blockFactory = $blockFactory; parent::__construct($context, $data, $jsonHelper, $directoryHelper); } 

i extended it and my construct is :

class PreviewButton extends OriginalPreviewButton { protected $_directoryHelper;

public function __construct( \Magento\Backend\Block\Template\Context $context, \Magento\Framework\View\Element\BlockFactory $blockFactory, array $data = [], ?SecureHtmlRenderer $jsonHelper = null, ?DirectoryHelper $directoryHelper = null ) { OriginalPreviewButton::__construct($context, $blockFactory, $data, $jsonHelper); $this->blockFactory = $blockFactory; } 

but i am still getting the same error. Can someone help to fix the error? Thanks in advance
