Что значит Undefined index: IBLOCK_CODE?

Участок кода вызывающий ошибку:
       $resExistingHalls = CIBlockElement::GetList(
           Array("SORT"=>"ASC"  ;)  ,
           Array(
               "IBLOCK_ID"            => $iblockIdHalls,
               "PROPERTY_CINEMA"    => $cinemaElementID,
           ),
           false,
           false,
           Array("IBLOCK_ID", "NAME", "PROPERTY_CINEMA", "PROPERTY_".$iblockPropID, "XML_ID"  ;)  
       );
