Can't buy product for some reason

Help and Feedback Scripting Support
#1

I have a script that buys an item and does something when its bought but for some reason it just gives the purchase failed error.

local marketplace = game:GetService("MarketplaceService")
local productId = 955894489
local player = game.Players.LocalPlayer

-- Function to handle the purchase
local function onProductPurchaseFinished(userId, purchasedProductId, isPurchased)
	if isPurchased and purchasedProductId == productId then
		-- Find all players excluding the buyer
		local otherPlayers = {}
		for _, otherPlayer in pairs(game.Players:GetPlayers()) do
			if otherPlayer ~= player then
				table.insert(otherPlayers, otherPlayer)
			end
		end

		-- Check if there are any other players available
		if #otherPlayers > 0 then
			-- Choose a random player from the list
			local randomPlayer = otherPlayers[math.random(1, #otherPlayers)]

			-- Create an explosion at the random player's character
			if randomPlayer.Character then
				local explosion = Instance.new("Explosion")
				explosion.Position = randomPlayer.Character.HumanoidRootPart.Position
				explosion.BlastRadius = 10
				explosion.BlastPressure = 500000
				explosion.Parent = randomPlayer.Character
			end
		end
	end
end

-- Connect the purchase prompt to the button click
script.Parent.MouseButton1Click:Connect(function()
	marketplace:PromptProductPurchase(player, productId)
end)

-- Listen for the product purchase completion
marketplace.PromptProductPurchaseFinished:Connect(onProductPurchaseFinished)

okay well, first off, this is a local script where you try to explode other players (this wont work!)

You also call purchase on the client and use PromptProductPurchaseFinished
Most of this script should be on the server and you should use ProcessReceipt Instead
