Here:

local products = {

Trophy5 = {
	id = 1387569055,
	func = function(plr)
		plr.leaderstats["🏆Trophy"].Value += 5
	end,
},

Trophy20 = {
	id = 1387569112,
	func = function(plr)
		plr.leaderstats["🏆Trophy"].Value += 20
	end,
},

Trophy50 = {
	id = 1387569223,
	func = function(plr)
		plr.leaderstats["🏆Trophy"].Value += 50
	end,
},

Trophy100 = {
	id = 1387569412,
	func = function(plr)
		plr.leaderstats["🏆Trophy"].Value += 100
	end,
},

Trophy200 = {
	id = 1387569455,
	func = function(plr)
		plr.leaderstats["🏆Trophy"].Value += 200
	end,
},

Trophy500 = {
	id = 1387569517,
	func = function(plr)
		plr.leaderstats["🏆Trophy"].Value += 500
	end,
},

Trophy1K = {
	id = 1387569594,
	func = function(plr)
		plr.leaderstats["🏆Trophy"].Value += 1000
	end,
},

Trophy2K = {
	id = 1387569645,
	func = function(plr)
		plr.leaderstats["🏆Trophy"].Value += 2000
	end,
},

}

local MarketPlaceService = game:GetService(“MarketplaceService”)

function MarketPlaceService.ProcessReceipt(receipt)
local devProductId = receipt.ProductId
local plr = game.Players:GetPlayerByUserId(receipt.PlayerId)
for i, product in pairs(products) do
if product.id == devProductId then
local succ, err = pcall(function()
product.func(plr)
end)

	end
end
return Enum.ProductPurchaseDecision.PurchaseGranted

end

NOTE: im not getting any errors

function -- why?? 

MarketPlaceService.ProcessReceipt(receipt)
local devProductId = receipt.ProductId
local plr = game.Players:GetPlayerByUserId(receipt.PlayerId)
for i, product in pairs(products) do
if product.id == devProductId then
local succ, err = pcall(function()
product.func(plr)
end)

Updated code

MarketPlaceService.ProcessReceipt = function(receipt)
local devProductId = receipt.ProductId
local plr = game.Players:GetPlayerByUserId(receipt.PlayerId)
for i, product in pairs(products) do
if product.id == devProductId then
local succ, err = pcall(function()
product.func(plr)
end)

Remember ProcessReceipt is a callback, it isn’t a function. This is the big mistake.

Here is the LocalScript i use for the Text Buttons that prompt the dev product, you can check if there is any problem here

productId = 1387569055

local mkp = game:GetService(“MarketplaceService”)

script.Parent.MouseButton1Click:Connect(function()

mkp:PromptProductPurchase(game.Players.LocalPlayer,productId)

end)

Nvm i found the fix!. If anyone also has a similar problem, it’s probably because you have more than one script for Developer Products! Make sure you only have one server script that processes reciepts
