fatal error

[LoveHate 0]

I have a payment gateway that unfortunately does not work with php8 or higher. After selecting the payment method, I get a white screen error. To check this problem, I enabled error display and saw the following error:

 Fatal error: Declaration of IPS\nexus\Gateway\_zarinpal::checkValidity(IPS\nexus\Money $amount, ?IPS\GeoLocation $billingAddress = null, ?IPS\nexus\Customer $customer = null) must be compatible with IPS\nexus\_Gateway::checkValidity(IPS\nexus\Money $amount, ?IPS\GeoLocation $billingAddress = null, ?IPS\nexus\Customer $customer = null, $recurrings = []) in /home/smooksh1/test.smook.shop/applications/nexus/sources/Gateway/zarinpal/zarinpal.php on line 26

zarinpal.php
