Process Receipt Issue

Help and Feedback Scripting Support
#1

I have been making a script that gives players a reward when they buy a developer product, however I keep getting this error: ServerScriptService.PlayerManager:54: attempt to index nil with ‘PlayerId’ and I don’t know why it is happening. I have made this exact script before and it worked perfectly.
This is some of the script:

local function processReceipt(receipt)
	print(receipt.PlayerId, receipt.ProductId)
	--receipt has: PlayerId, PurchaseId, ProductId, CurrencySpentValue, CurrencyType, PlaceIdWherePurchased
	local ID = receipt.PlayerId .. "-" .. receipt.PurchaseId
	
	local success = nil
	pcall(function()
		success = previousPurchases:GetAsync(ID)
	end)
	
	if success then
		--they have bought it
		return Enum.ProductPurchaseDecision.PurchaseGranted
	end

However it errors on the print statement because there is no PlayerId. Thanks in advance for any help!

Can you show where your setting the ProcessReceipt callback for MarketPlace Service, also, ensure that your only setting it once.

This is the whole script:

local function processReceipt(receipt)
	print(receipt.PlayerId, receipt.ProductId)
	--receipt has: PlayerId, PurchaseId, ProductId, CurrencySpentValue, CurrencyType, PlaceIdWherePurchased
	local ID = receipt.PlayerId .. "-" .. receipt.PurchaseId
	
	local success = nil
	pcall(function()
		success = previousPurchases:GetAsync(ID)
	end)
	
	if success then
		--they have bought it
		return Enum.ProductPurchaseDecision.PurchaseGranted
	end
	
	local player = game.Players:GetPlayerByUserId(receipt.PlayerId)
	if not player then
		--they left or disconnected
		return Enum.ProductPurchaseDecision.NotProcessedYet
		
	else
		print("Found Player!")
		if receipt.ProductId == donationId then
			--give them a cheese
			local cheese = gear.Cheese:Clone()
			cheese.Parent = player:WaitForChild("Backpack")
			cheese.Handle.Cheese.PlaybackSpeed = math.random(0.7,1.4)
		end
		
		pcall(function()
			previousPurchases:SetAsync(ID, true)
		end)
		
		return Enum.ProductPurchaseDecision.PurchaseGranted
	end
	
end

marketPlaceService.ProcessReceipt = processReceipt()

Your setting the callback incorrectly in this line:

marketPlaceService.ProcessReceipt = processReceipt()
--should be:
marketPlaceService.ProcessReceipt = processReceipt
