v1.3.0: How to fix incompatible issue with M2.4.2?

QUESTION:

I use the module v1.3.0 on my site and it works fine. 

However, after I upgrading my site to Magento 2.4.2, when I open the product configurable, it shows error:

] main.CRITICAL: TypeError: Argument 1 passed to Magento\Catalog\Pricing\Price\CalculateCustomOptionCatalogRule::execute() must be an instance of Magento\Catalog\Model\Product, null given, called in /var/www/vhosts/lockstation.co.uk/htdocs/vendor/magento/module-catalog/Model/Product/Option/Value.php on line 270 and defined in /xxx/xxxx/xxxx/xxxx/xxxx/vendor/magento/module-catalog/Pricing/Price/CalculateCustomOptionCatalogRule.php:49
