it's not a 1.x error, it's a general lua error
if player:getSlotItem(CONST_SLOT_FEET) returns a nil value (only happens if the player doesn't have an item in that slot) then indexing (using the dot) for itemid will throw "attempt to index a nil value"
so you need to check if the item exists before indexing it
Lua: 
function onCastSpell(creature, var)
    local player = Player(creature)
    if not player then
        return false
    end
    local item = player:getSlotItem(CONST_SLOT_FEET)
    if item then -- we need to make sure the item exists before we attempt to index for itemid
        if item.itemid == 2195 then
            creature:sendTextMessage(MESSAGE_STATUS_DEFAULT, "OK1")
            creature:getPosition():sendMagicEffect(CONST_ME_MAGIC_GREEN)
        elseif item.itemid == 2643 then
            creature:sendTextMessage(MESSAGE_STATUS_DEFAULT, "OK2")
            creature:getPosition():sendMagicEffect(CONST_ME_MAGIC_GREEN)

you're not comparing the storage value to any number, that's why it doesn't work
player:getStorageValue(storage) == number

if item.itemid == 2195 and player:getStorageValue(storage) == 1 then

Work Storage check but if you dont have storage spell spent mana and say words and dont say NO
