Lua deco npc errors

[Obito]

I have this deco NPC script and it gives me an error while I talk with the NPC

Lua Script Error: [Npc interface]
data/npc/scripts/furniture.lua:onCreatureSay
LuaScriptInterface::getNumber(). Argument -1 has out-of-range value for unsigned int: -1
stack traceback:

This my script

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)

-- OTServ event handling functions start
function onCreatureAppear(cid)                npcHandler:onCreatureAppear(cid) end
function onCreatureDisappear(cid)             npcHandler:onCreatureDisappear(cid) end
function onCreatureSay(cid, type, msg)     npcHandler:onCreatureSay(cid, type, msg) end
function onThink()                         npcHandler:onThink() end
-- OTServ event handling functions end

-- Don't forget npcHandler = npcHandler in the parameters. It is required for all StdModule functions!

keywordHandler:addKeyword({'chairs'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I sell wooden, sofa, red cushioned, green cushioned, tusk and ivory chairs.'})
keywordHandler:addKeyword({'tables'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I sell big, square, round, small, stone, tusk, bamboo tables.'})
keywordHandler:addKeyword({'plants'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I sell pink and green flowers, also christmas trees.'})
keywordHandler:addKeyword({'furniture'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I sell large trunks, boxes, drawers, dressers, lockers and troughs.'})
keywordHandler:addKeyword({'more'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I sell coal basins, birdcages, harps, pianos, globes, clocks and lamps.'})
keywordHandler:addKeyword({'tapestries'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I sell blue, green, orange, pink, red, white and yellow tapestries.'})

keywordHandler:addKeyword({'small'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I sell small purple, small green, small red, small blue, small orange, small turquiose and small white pillows.'})
keywordHandler:addKeyword({'round'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I sell round blue, round red, round purple and round turquiose pillows.'})
keywordHandler:addKeyword({'square'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I sell blue, red, green and yellow pillows.'})
keywordHandler:addKeyword({'pillows'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I sell heart, small, sqare and round pillows.'})

-- Makes sure the npc reacts when you say hi, bye etc.
npcHandler:addModule(FocusModule:new())
