So it's probably because you're mis-clicking onto the ground, or into a backpack or something, and getting an item instead of a creature.

Sooo, we just need to add a check to ensure the potion is being used on a creature.

try this

change
Lua:
function onUse(player, item, fromPosition, target, toPosition, isHotkey)
    if type(target) == "userdata" and not target:isPlayer() then
        return false
    end
to
Lua:
function onUse(player, item, fromPosition, target, toPosition, isHotkey)
    if not target:isCreature() then
        return false
    end
    if type(target) == "userdata" and not target:isPlayer() then
        return false
    end

well, I tested it and apparently there was no error, I don't know what the players are doing to make this error occur, I'll wait to see if it happens again, thank you very much, Xikini
