Lua Antidote Potion Bug

[Bill3000]

My Antidote Potion cures poison, but don't add an empty potion when used:

local EMPTY_POTION = 7636
 
local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
setCombatParam(combat, COMBAT_PARAM_TARGETCASTERORTOPMOST, true)
setCombatParam(combat, COMBAT_PARAM_AGGRESSIVE, false)
setCombatParam(combat, COMBAT_PARAM_DISPEL, CONDITION_POISON)
 
local exhaust = createConditionObject(CONDITION_EXHAUST)
setConditionParam(exhaust, CONDITION_PARAM_TICKS, getConfigInfo('timeBetweenExActions'))
 
function onUse(cid, item, fromPosition, itemEx, toPosition)
        if(not isPlayer(itemEx.uid)) then
                return false
        end
 
        if(hasCondition(cid, CONDITION_EXHAUST_HEAL)) then
                doPlayerSendDefaultCancel(cid, RETURNVALUE_YOUAREEXHAUSTED)
                return true
        end
 
        if(not doCombat(cid, combat, numberToVariant(itemEx.uid))) then
                return false
        end
 
        doAddCondition(cid, exhaust)
        doCreatureSay(itemEx.uid, "Aaaah...", TALKTYPE_ORANGE_1)
 
        doRemoveItem(item.uid, 1)
        if(fromPosition ~= CONTAINER_POSITION) then
                doCreateItem(potion.empty, fromPosition)
        else
                doPlayerAddItem(cid, potion.empty, 1)
        end
 
        return true
end

This is the console error:

antidote_potion.lua:31: attemptto index global 'potion' <a nil value>

Use EMPTY_POTION instead of potion.empty.

Try

doCreateItem(EMPTY_POTION,1,fromPosition)
