[Error - NpcScript Interface]

[Mr Tuzzz]

Hello people! i'm returning to the world of ot after many years and i'm trying to host a 7.6 server just for fun, mostly for my friends but will open it up for any1! However, i'm getting a Npc error when i launch the server and i dont have the skills to solve it.
The server is The OTX Server Version: (2.100)
and the error in question is as follows.
"
[7/12/2025 20:25:37] [Error - NpcScript Interface]
[7/12/2025 20:25:37] data/npc/scripts/default.lua

All the Npcs react when you say hi to them but nothing happend when i try to buy runes for example.

as far as my knowledge goes this is the part of the modules.lua that it's refering to?

-- Adds a new buyable item.
    --    names = A table containing one or more strings of alternative names to this item. Used only for old buy/sell system.
    --    itemid = The itemid of the buyable item
    --    cost = The price of one single item
    --    subType - The subType of each rune or fluidcontainer item. Can be left out if it is not a rune/fluidcontainer. Default value is 0 and 1 (depending on shop mode)
    --    realName - The real, full name for the item. Will be used as ITEMNAME in MESSAGE_ONBUY and MESSAGE_ONSELL if defined. Default value is nil (getItemNameById will be used)
    function ShopModule:addBuyableItem(names, itemid, cost, subType, realName)
        if(type(subType) == 'string' and realName == nil) then
            realName = subType
            subType = nil
        end

        local v = getItemInfo(itemid)
        if(SHOPMODULE_MODE ~= SHOPMODULE_MODE_TALK) then
            local item = {
                id = itemid,
                buy = cost,
                sell = -1,
                subType = tonumber(subType) or (v.charges > 0 and v.charges or 0),
                name = realName or v.name
            }

            for i, shopItem in ipairs(self.npcHandler.shopItems) do
                if(shopItem.id == item.id and (shopItem.subType == item.subType or shopItem.subType == 0)) then
                    if(item.sell ~= shopItem.sell) then
                        item.sell = shopItem.sell
                    end

                    self.npcHandler.shopItems[i] = item
                    item = nil
                    break
                end
            end

            if(item ~= nil) then
                table.insert(self.npcHandler.shopItems, item)
            end
        end

        if(names ~= nil and SHOPMODULE_MODE ~= SHOPMODULE_MODE_TRADE) then
            local parameters = {
                itemid = itemid,
                cost = cost,
                eventType = SHOPMODULE_BUY_ITEM,
                module = self,
                realName = realName or v.name,
                subType = tonumber(subType) or (v.charges > 0 and v.charges or 1)
            }

            for i, name in pairs(names) do
                local keywords = {}
                table.insert(keywords, 'buy')
                table.insert(keywords, name)

                local node = self.npcHandler.keywordHandler:addKeyword(keywords, ShopModule.tradeItem, parameters)
                node:addChildKeywordNode(self.yesNode)
                node:addChildKeywordNode(self.noNode)
            end
        end
    end

I would really appreciate if some kind soul could help me find a solution for this.
Thank you
