Undefined array key “SERVER_PROTOCOL” when running Cron

After installing Weglot I have started getting error message while running cron:

I get following error message when runnin cron PHP Warning: Undefined array key “SERVER_PROTOCOL” in /var/www/vhosts/droix.net/httpdocs/wp-content/plugins/weglot/vendor/weglot/weglot-php/src/Util/Server.php on line 122 PHP Warning: Undefined array key “SERVER_PROTOCOL” in /var/www/vhosts/droix.net/httpdocs/wp-content/plugins/weglot/vendor/weglot/weglot-php/src/Util/Server.php on line 122 PHP Warning: Undefined array key “SERVER_PROTOCOL” in /var/www/vhosts/droix.net/httpdocs/wp-content/plugins/weglot/vendor/weglot/weglot-php/src/Util/Se…

after providing a default value for SERVER_PROTOCOL issue seems to be gone, however I would like your support to look into it and include that fix in future releases

public static function getProtocol(array $server)
{
$protocol = isset($server[‘SERVER_PROTOCOL’]) ? strtolower($server[‘SERVER_PROTOCOL’]) : ‘http’;
return substr($protocol, 0, strpos($protocol, ‘/’)) . (self::isSsl($server) ? ‘s’ : ”);
}
