MarketplaceService:PromptProductPurchase(PLAYER1, SOME_PRODUCT_ID)

Error: ( doesn’t prompt)

‘game:GetService(“MarketplaceService”):PromptProductPurchase(PLAYER2, 16427305037) - Studio
13:20:21.208 MarketplaceService:PromptProductPurchase() player should be of type Player’

I can get my friend to test in 10 minutes so that may just be easier, I’ll let you know if I get any error messages.

Ok so I got a few error messages and I added print statements in places so you can see where the script got to:

I got that same error with player should be type player, I don’t know if it happened every time (I clicked on the button to buy different t shirts a couple times) but it popped up when I clicked the button one of the times.

Edit: I thought u might want to see the local script

local Ms = game:GetService("MarketplaceService")

local button = script.Parent

button.MouseButton1Click:Connect(function()
	
	local player = game.Players.LocalPlayer
	local itemId = button.Value.Value
	local itemPrice = button.Price.Value
	
	Ms:PromptPurchase(player, itemId)
	
	Ms.PromptPurchaseFinished:Connect(function(player, itemId, was_purchased)
		
		if was_purchased then
			
			type creator = {CreatorTargetId: number, CreatorType: string, 
				HasVerifiedBadge: boolean, Id: number, Name: string}

			local function getItemCreator(itemId: number): creator
				local info = Ms:GetProductInfo(itemId)
				return info.Creator
			end
			
			local creator = getItemCreator(itemId)
			local winnerName = creator.Name
			
			local text = "[SYSTEM] "..player.." donated "..itemPrice.." robux to "..winnerName
			game.Workspace.SystemMessage:FireServer(text, itemPrice)
		end

	end)
end)

Actually I’ve managed to get it to a point where its detecting the purchase, however, It worked perfectly the first time, I bought an item that cost 5 and it added 5 to the leaderstat, but now its doubling whatever the actual item price is? Any idea why? (For example I donate 10, it adds 20 to the leaderstat)

local function onPromptPurchaseFinished(player, assetId, isPurchased)
						if isPurchased then
							local asset = MarketPlaceService:GetProductInfo(assetId)
							local leaderstats = player.leaderstats
							local donated = leaderstats.Donated
							donated.Value += asset.PriceInRobux
						else
							print("Not Purchased")
						end
					end

					MarketPlaceService.PromptPurchaseFinished:Connect(onPromptPurchaseFinished)
					
					local function donateButtonClicked(donateButton, loser)
						local itemId = donateButton.Value.Value
						MarketPlaceService:PromptPurchase(loser, itemId)
						return
					end

					for i,v in pairs(loser.PlayerGui.Donation.Frame.itemsScroller:GetChildren()) do
						if not (v:IsA("TextButton") or v:IsA("ImageButton")) then continue end
						v.MouseButton1Click:Connect(function()
							donateButtonClicked(v, loser)
						end)
					end
