little npc quest problem

[BulawOw]

So i was trying to make my first part of quest that gonna just start the quest but as always a problem and idk why so there is the script for that quest

local function creatureSayCallback(cid, type, msg)
   if not npcHandler:isFocused(cid) then
       return false
   end
   local player = Player(cid)
   if msgcontains(msg, "mission") then
       if player:getStorageValue(Storage.HiddenMonster.QuestLine) < 1 then
           npcHandler:say("tutaj bedzie historia", cid)
           npcHandler.topic[cid] = 0
       end
   end
end

And there is a error when i say to npc "mission". No idea if this gonna help but i use the latest forgotten server from github.
