Developer Product processReceipt not being passed productInfo

Help and Feedback Scripting Support

I have a button that when clicked, prompts the purchas of a dev product. Strangely the receiptInfo doesn’t seem to be passed to the function.

Here’s the error given: ... attempt to index nil with 'PlayerId'

Server Script:

local MarketPlace = game:GetService('MarketplaceService')
local Players = game:GetService('Players')
local productID = 1094898392

local ServerStorage = game:GetService('ServerStorage')
local sword = ServerStorage:WaitForChild('ClassicSword')

local function processReceipt(receiptInfo)

	local player = Players:GetPlayerByUserId(receiptInfo.PlayerId)
	if not player then
		-- player left game
		-- if they come back, this will be called again
		
		return Enum.ProductPurchaseDecision.NotProcessedYet
	else
		if receiptInfo.ProductId == productID then
			local swordClone = sword:Clone()
			swordClone.Parent = player.Character
			print(player.Name .. ' just bought a nice ol\' sword!')
		end
	end
	
	return Enum.ProductPurchaseDecision.PurchaseGranted
end

-- Set Callback
MarketPlace.ProcessReceipt = processReceipt()

Localscript

local MarketPlace = game:GetService('MarketplaceService')
local Players = game:GetService('Players')
local productID = 1094898392

local player = Players.LocalPlayer

script.Parent.MouseButton1Click:Connect(function ()
	MarketPlace:PromptProductPurchase(player, productID)
end)

You’re supposed to pass the function itself, instead of calling it:

MarketPlace.ProcessReceipt = processReceipt
