Lua [TFS 1.0] NPC (onCreatureSay)

[Sentinel3]

Hi everyone,

Well you know guys that Christmas is here soon , so I decided to create the NPC (Santa Claus) for reward the players who connect during Christmas.

About NPC, all works perfect except this error:

Using: Lastest version of TFS 1.0

Error I got in console:

Lua Script Error: [Npc interface]

    else
        npcHandler:say('I already gave you the gift, come back next year. HO HO HO!', cid)
end
    else
        npcHandler:say('Come back when you being a good guy.', cid)
end
        npcHandler:resetNpc()
    return true
end

        npcHandler:setMessage(MESSAGE_GREET, "HO HO HO I am Santa Claus. Merry Christmas |PLAYERNAME|!. I will give you a gift for being a good guy.")

    local noNode = KeywordNode:new({'no'}, santaNPC, {present = false})
    local yesNode = KeywordNode:new({'yes'}, santaNPC, {present = true})

    local node = keywordHandler:addKeyword({'pre'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'You were good this year?'})
          node:addChildKeywordNode(yesNode)
          node:addChildKeywordNode(noNode)
          npcHandler:addModule(FocusModule:new())

Thank you so much, I hope that someone can help me!

getItemByNameId(reward) to getItemNameById(reward)
also if u'r using 1.0 just use getItemName
