OTClient Store doesnt work

[Ciosny]

Hi! I have a problem with my store.

I added the store to my folders but i have error in otclientv8.log:
Warning: 'categories' exists, but it has no children!
Error: Cannot focus on the first category. It does not exist.

in the game displays an empty store with no category

OTS>data>scripts>store>game_store.lua

I have TFS 1.4.2 OTCv8

for example, I am posting a code fragment:

local DONATION_URL = "https://website.com/donate.php"
local CODE_GAMESTORE = 102
local GAME_STORE = nil
local LoginEvent = CreatureEvent("GameStoreLogin")
function LoginEvent.onLogin(player)
player:registerEvent("GameStoreExtended")
return true
end
function gameStoreInitialize()
GAME_STORE = {
categories = {},
offers = {}
}
addCategory("Items", "Tools, Dolls & Boxes.", "item", 2640)
addItem("Items", "Premium Scroll", "Premium account for 30 days.", 5546, 1, 600)
addItem("Items", "Weekly Premium Scroll", "Premium account for 7 days.", 5545, 1, 200)
addCategory(
"Outfits",
"Contains all addons.",
"outfit",
{
mount = 0,
type = 131,
addons = 0,
head = 0,
body = 114,
legs = 85,
feet = 76
}
)
addOutfit(
"Outfits",
"Citizen",
"Citizen",
{
mount = 0,
type = 128,
addons = 3,
head = 114,
body = 114,
legs = 114,
feet = 114
},
{
mount = 0,
type = 136,
addons = 3,
head = 114,
body = 114,
legs = 114,
feet = 114
},
