Roblox's VIP door model isn't working?

I used Roblox's VIP door model for my game but it's not working. In the output it says GamePassId '4429482' is not of type Game Pass. Please use MarketplaceService:PlayerOwnsAsset instead but when I use MarketplaceService and add the variable nothing happens. Even the output is blank. This is Roblox's script:

--------------------
--| WaitForChild |--
--------------------

-- Waits for parent.child to exist, then returns it
local function WaitForChild(parent, childName)
    assert(parent, "ERROR: WaitForChild: parent is nil")
    while not parent:FindFirstChild(childName) do parent.ChildAdded:wait() end
    return parent[childName]
end

-----------------
--| Variables |--
-----------------

local GamePassService = game:GetService('GamePassService')
local PlayersService = game:GetService('Players')

local VipDoor = script.Parent

local GamePassIdObject = WaitForChild(script, 'GamePassId')

local JustTouched = {}

-----------------
--| Functions |--
-----------------

-- Finds out which side the player is on and teleports them to the other
local function TeleportToOtherSide(character, hitPart)
    local bottomOfDoor = VipDoor.CFrame.p - Vector3.new(0, VipDoor.Size.Y / 2, 0)
    local inFrontOfDoor = bottomOfDoor + VipDoor.CFrame.lookVector * 3
    local behindDoor = bottomOfDoor - VipDoor.CFrame.lookVector * 3

    local distanceToFront = (inFrontOfDoor - hitPart.Position).magnitude
    local distanceToBack = (behindDoor - hitPart.Position).magnitude
    if distanceToFront < distanceToBack then
        character:MoveTo(behindDoor)
    else
        character:MoveTo(inFrontOfDoor)
    end
end

-- When a player with the game pass touches the door, teleport them to the other side
local function OnTouched(otherPart)
    if otherPart and otherPart.Parent and otherPart.Parent:FindFirstChild('Humanoid') then
        local player = PlayersService:GetPlayerFromCharacter(otherPart.Parent)
        if player and not JustTouched[player] then
            JustTouched[player] = time()
            if GamePassService:PlayerHasPass(player, GamePassIdObject.Value) then
                TeleportToOtherSide(player.Character, otherPart)
            end
        end
    end
end

-- Removes old entries in JustTouched
local function RemoveOldTouches()
    for player, touchTime in pairs(JustTouched) do
        if time() > touchTime + 0.3 then
            JustTouched[player] = nil
        end
    end
end

--------------------
--| Script Logic |--
--------------------

VipDoor.Touched:connect(OnTouched)

while true do
    RemoveOldTouches()
    wait(1/30)
end

I need help desperately... I can't find a solution online. I checked that I put the correct value in the intvalue many times so it has to be correct. Help is GREATLY appreciated.
