Is anyone using PayPal Pro with PHP 8.1+? I'm getting a boatload of warnings about undefined array keys.

Code:
[11-Dec-2023 04:46:41 America/Los_Angeles] Request URI: /store/index.php?main_page=checkout_process, IP address: XXXXXXXXXXXXXX Language id 1
#0 /home/xxx/public_html/store/includes/modules/payment/paypaldp.php(1057): zen_debug_error_handler()
