TFS 1.X+ [TFS 1.5]Store item comes inside an additional backpack.

[Shoorkill]

Good, my dears! I made some unsuccessful attempts, I would like the store to deliver the items sold inside a backpack added by the store itself, the shop adds the backpack, but the items come outside of it!, can anyone help me with this?

function processBuy(player, data)
    local categoryId = tonumber(data["category"])
    local offerId = tonumber(data["offer"])
    local offer = SHOP_CATEGORIES[categoryId]['offers'][offerId]
    local callback = SHOP_CALLBACKS[categoryId][offerId]

    if not offer or not callback or data["title"] ~= offer["title"] or data["cost"] ~= offer["cost"] then
        sendJSON(player, "categories", SHOP_CATEGORIES) -- refresh categories, maybe invalid
        return sendMessage(player, "Error!", "Invalid offer")     
    end

    local points = getPoints(player)
    if not offer['cost'] or offer['cost'] > points or points < 1 then
        return sendMessage(player, "Error!", "You don't have enough points to buy " .. offer['title'] .."!", true)   
    end

    -- Criar uma mochila para itens comuns
    local backpack = nil
    if offer['type'] == 'item' then -- Check if it is a common item
        backpack = player:addItem(1988) -- Replace 1988 with backpack ID
        if backpack then
            backpack:setAttribute(ITEM_ATTRIBUTE_NAME, "Store Purchase")
        end
    end

    -- Call the callback to process the purchase
    local status = callback(player, offer, backpack)

    if status == true then   
        db.query("UPDATE `accounts` set `points` = `points` - " .. offer['cost'] .. " WHERE `id` = " .. player:getAccountId())
        db.asyncQuery("INSERT INTO `shop_history` (`account`, `player`, `date`, `title`, `cost`, `details`) VALUES ('" .. player:getAccountId() .. "', '" .. player:getGuid() .. "', NOW(), " .. db.escapeString(offer['title']) .. ", " .. db.escapeString(offer['cost']) .. ", " .. db.escapeString(json.encode(offer)) .. ")")
        return sendMessage(player, "Success!", "You bought " .. offer['title'] .."!", true)
    end

    if status == nil or status == false then
        status = "Unknown error while buying " .. offer['title']
    end
    sendMessage(player, "Error!", status)
end
