Why is my gamepass not prompting when I click on an image button?

I have created a script that should prompt a gamepass to the player when clicked on through and image button but it doesn't seem to be doing that. Not sure what went wrong and I need some help.

local MarketplaceService = game:GetService("MarketplaceService")

local MainFrame = script.Parent.MainFrame
local janitorGamepass = MainFrame.JanitorGamepassFrame.JanitorGamepass
local OpenShop = MainFrame.Parent.OpenShop

local player = game.Players.LocalPlayer

local janitorGamepassID = 8861359

janitorGamepass.MouseButton1Down:Connect(function()
    local success, message = pcall(function()
        hasPass = MarketplaceService:UserOwnsGamePassAsync(player.UserId, janitorGamepassID)
end)

    if hasPass then
        print("player alread has the gamepass")
    else
        MarketplaceService:PromptGamePassPurchase(player, janitorGamepassID)
    end
end)

OpenShop.MouseButton1Down:Connect(function()
    MainFrame.Visible = not MainFrame.Visible
end)
