Błąd z SKQuery

Pisałem sobie taki skrypt:

script options:
    $ init com.mysql.jdbc.Driver
    $ db url jdbc:mysql://[pewne dane]:3306/[pewne dane]
    $ db username [pewne dane]
    $ db password [pewne dane]
	
on join:
	set {_IP::%player%} to player's ip
	set {_czyZweryfikowany::%player%} to objects in column "tickets" from result of query "SELECT * FROM tickets WHERE ip = '%{_IP::%player%}%'" and close
	if {_czyZweryfikowany::%player%} is not set:

No i w konsolce mam taki error:

No i ze strony WWW wszystko działa, zapisuje się do MySQL itd. Zadaniem tego skryptu jest sprawdzeniem czy w bazie jest rekord z adresem IP użytkownika (gdzie ip = %{_Zmienna.z.IP.gracza}%). Tylko to nie działa (nie odczytuje). Poprawiłby mi to ktoś?? Z góry dzięki
