Why is my Promt Gamepass purchase script not work?

I have a Gui button when pressed it fires a remote event that is connected to a server script that prompts a game pass purchase:

In the local script inside the Gui button:

local RStorage = game:GetService("ReplicatedStorage")
local Event = RStorage:WaitForChild("RE1")
local Button = script.Parent

Button.Activated:Connect(function()
    print("Event Fired")
    Event:FireServer()
end)

and in the server script inside the ServerScriptService:

local GamePassService = game:GetService("GamePassService")
local RStorage = game:GetService("ReplicatedStorage")
local Event = RStorage:WaitForChild("RE1")
local MarketplaceS = game:GetService("MarketplaceService")

Event.OnServerEvent:Connect(function(player)
    MarketplaceS:PromptGamePassPurchase('6693488')
    print("All thisnss")
end)

and the error it gives.:

  Event Fired
  16:27:07.628 - Argument 2 missing or nil
16:27:07.631 - Stack Begin
16:27:07.633 - Script 'ServerScriptService.ServerSideGP:VIP', Line 7
16:27:07.635 - Stack End

--I dont know if this has to do anything:
16:25:16.767 - Go to Game Settings and turn on Allow HTTP requests.

Can someone fin the error and tell me it?
