UserOwnsGamePassAsync "not able to cast int64"?

Simple coding doesn't work. The error is

17:08:07.256 - Unable to cast Instance to int64 and so on, line 5 stack end

local market=game:GetService("MarketplaceService")
local player = game:GetService("Players").LocalPlayer
local button = script.Parent

if market:UserOwnsGamePassAsync(player,7218055) then
	button.Visible = true
else
	button.Visible = false
end

function activate()
		button.Parent.StoreFrame.Visible = not button.Parent.StoreFrame.Visible
end

script.Parent.MouseButton1Click:Connect(activate)

Am i using this function right? Why can't it get the "int64"?

(localscript)
