Deprecated Functionality: Optional parameter $data declared

Question

We're in the process of upgrading our store from Magento 2.4.2 to 2.4.4 and encountered the error shown in the image below. Please help us fix this issue.

Script in the project folder:

<?php

namespace StripeIntegration\Payments\Block\Customer;

use Magento\Framework\App\Filesystem\DirectoryList;
use Magento\Framework\Filesystem;
use Magento\Framework\View\Element;
use StripeIntegration\Payments\Helper\Logger;

class Cards extends \Magento\Framework\View\Element\Template
{
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        array $data = [],
        \StripeIntegration\Payments\Helper\Generic $helper,
        \Magento\Payment\Block\Form\Cc $ccBlock,
        \StripeIntegration\Payments\Model\Config $config
    ) {
        $this->stripeCustomer = $helper->getCustomerModel();
        $this->helper = $helper;

        $this->ccBlock = $ccBlock;
        $this->config = $config;

        parent::__construct($context, $data);
    }

    public function getCards()
    {
        try
        {
            return $this->stripeCustomer->getCustomerCards();
        }
        catch (\Exception $e)
        {
            $this->helper->addError($e->getMessage());
            $this->helper->logError($e->getMessage());
            $this->helper->logError($e->getTraceAsString());
        }
    }

    public function verifyBillingAddress()
    {
        $address = $this->helper->getCustomerDefaultBillingAddress();

        if (!$address || empty($address->getStreet()))
            return false;

        return true;
    }

    public function getCcMonths()
    {
        return $this->ccBlock->getCcMonths();
    }

    public function getCcYears()
    {
        return $this->ccBlock->getCcYears();
    }

    public function cardType($code)
    {
        return $this->helper->cardType($code);
    }
}

Answer 1

This is means that in your block you define optional argument before another required, like:

public function __construt($data = [], SomeClass $required)
{
    //...
}

You need to change order of variables to first required and only after optional (predefined)

public function __construt(SomeClass $required, $data = [])
{
    //...
}

[Update]

In your case it should be

// ...
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \StripeIntegration\Payments\Helper\Generic $helper,
        \Magento\Payment\Block\Form\Cc $ccBlock,
        \StripeIntegration\Payments\Model\Config $config,
        array $data = []
    ) {
        $this->stripeCustomer = $helper->getCustomerModel();
        $this->helper         = $helper;
        $this->ccBlock        = $ccBlock;
        $this->config         = $config;

        parent::__construct($context, $data);
    }
// ...

Answer 2

you can use ?type instead in your case : ?array $data, read more here: https://php.watch/versions/8.0/deprecate-required-param-after-optional
