PHP 8.2 Fatal error

Dobrý deň, pozdravujem výrobcov a ďakujeme za super plugin, po aktualizácii e-shopu z PHP 7.4.33 na PHP 8.2.5 mi začalo vyhadzovať error PHP Fatal error: Uncaught TypeError: strtotime(): Argument #2 ($baseTimestamp) must be of type ?int, string a prestalo generovať štítky. Skúšal som dať nižšie verzie PHP 8.0, 8.1 ale až keď sme dali naspäť 7.4 tak to znova prešlo a štítky vygenerovalo. Prikladám error z logu: 1619482#0: ***565011 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught TypeError: strtotime(): Argument #2 ($baseTimestamp) must be of type ?int, string given in /var/www/vhosts/***/httpdocs/wp-content/plugins/invelity-gls-online-connect/classes/class.invelityGlsOnlineConnectProcess.php:121 Stack trace: #0 /var/www/vhosts/***/httpdocs/wp-content/plugins/invelity-gls-online-connect/classes/class.invelityGlsOnlineConnectProcess.php(121): strtotime() #1 /var/www/vhosts/***/httpdocs/wp-includes/class-wp-hook.php(308): InvelityGlsOnlineConnectProcess->custom_bulk_action() #2 /var/www/vhosts/***/httpdocs/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters() #3 /var/www/vhosts/***/httpdocs/wp-includes/plugin.php(517): WP_Hook->do_action() #4 /var/www/vhosts/***/httpdocs/wp-admin/admin.php(385): do_action() #5 /var/www/vhosts/***/httpdocs/wp-admin/edit.php(10): require_once('...') #6 {main} thrown in /var/www/vhosts/***/httpdocs/wp-content/plugins/invelity" while reading response header from upstream
