Error cron debian 10

When running cron on debian 10 at the bottom of the page it shows the error:
An Error Was Encountered
Call to undefined function mysqli_connect

Another important detail is that in debian 10 if I give the command php -v it shows: PHP 8.1.2

cd /opt/ASTPP/web_interface/astpp/cron/ && php cron.php crons

You are just going to have to put in an issue. They claimed the script for Debian 10 is tested and working, but I say differently.

https://jira.astppbilling.org/

@dbbrito , we have applied few patches for above problem. Will update the script by tomorrow and then you can download latest script.
