PHP 8.4 compat issue in 1.8.3

[evs-xsarus]

  Deprecated Functionality: MagePal\CustomShippingRate\Config\Backend\Serialized\ArraySerialized::__construct(): Implicitly marking parameter $resource as nullable is deprecated, the explicit nullable type mu  
  st be used instead in /sites/dlk_upgrade/magento/vendor/magepal/magento2-customshippingrate/Config/Backend/Serialized/ArraySerialized.php on line 40 

Could this be fixed.
