how to Prompt Game Pass purchase on part touch?

Hello, I am developing a game and there is a wall which you can only pass if you have bought a gamepass. The problem is that i tested it out with a friend but the wall was not there even tho he didnt purchase the game pass.

I've put a local script into the wall and it's

script.Parent.Touched:Connect(function(hit)
    game:GetService("MarketplaceService"):PromptGamePassPurchase(game.Players.LocalPlayer, 18801304)
end)

I've also put a script into serverscriptservice which does :

 local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")
local conveyorGamepassID = 18801304

game.Players.PlayerAdded:Connect(function(player)
    local success, message = pcall(function()
        hasPass = MarketplaceService:UserOwnsGamePassAsync(player.UserId, conveyorGamepassID)
    end)
    if hasPass then
        print("player has the gamepass")

        game.Workspace.MainBuild.MainConveyor.ConveyorBorder.CanCollide = false
    end
end)

local function onPromptGamePassPurchaseFinished(player, purchasedPassID, purchaseSuccess)
    if purchaseSuccess == true and purchasedPassID == conveyorGamepassID then
        print(player.Name .. " purchased the game pass!")

        game.Workspace.MainBuild.MainConveyor.ConveyorBorder.CanCollide = false
    end
end

MarketplaceService.PromptGamePassPurchaseFinished:Connect(onPromptGamePassPurchaseFinished)

Could anyone please help?
