Problem related to Developer Products! [IN LIVE GAME]

I’m facing a very weird problem related to Developer Products.
In Roblox studio everything works fine, but in the live game it shows an error when i attempt to purchase a dev product. Does anyone know more about this issue?

So this a local script that handles a gui and prompts the product id

for i, LeftBarButtons in pairs(MainGui.MainThings.LeftBar.DevProducts:GetChildren()) do
	if LeftBarButtons:IsA("ImageButton") then 
		LeftBarButtons.MouseButton1Click:Connect(function()
			for i, v in pairs(ProductsModule.Product) do
				if v.Genre == "Product" and v.ProductName == LeftBarButtons.Name then 
					Mps:PromptProductPurchase(Player, v.Id)
				end
			end
		end)
	end
end

What is the error that it displays?

There is no error, that’s the thing :(((
