Extra parameters passed to parent construct $directoryHelper

I am getting the following error on di compile:

**Extra parameters passed to parent construct $directoryHelper**

That’s the original code:

class PreviewButton extends MagentoConfigBlockSystemConfigFormField
{
    
    protected $blockFactory;
   
    public function __construct(
        MagentoBackendBlockTemplateContext $context,
        MagentoFrameworkViewElementBlockFactory $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(
        MagentoBackendBlockTemplateContext $context,
        MagentoFrameworkViewElementBlockFactory $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
