Error in my code - purchase failing because something went wrong?

I'm making a gamepass GUI shop for my game and I cannot find the error, however when I try to buy a gamepass I get this text:

"Your purchase failed because something went wrong. Your account has not been charged. Please try again later."

Here is my PurchaseScript

local MarketplaceService = game:GetService("MarketplaceService")

--[TOOLS]
local tools = game.ServerStorage.Tools

--[id] = ToolName
local list = {
    [21842414] = "GravityCoil",,
    [21842376] = "SpeedCoil",
    [90075532] = "SuperCoil",
}
local skip = 1179259924

local function processReceipt(receiptInfo)

    local player = game:GetService("Players"):GetPlayerByUserId(receiptInfo.PlayerId)
    if not player then
        -- The player probably left the game
        -- If they come back, the callback will be called again
        return Enum.ProductPurchaseDecision.NotProcessedYet
    end

    print(receiptInfo.PlayerId .. " just bought " .. receiptInfo.ProductId)

    local sound = Instance.new("Sound", player)
    sound.SoundId = "rbxassetid://254003734"
    sound.PlayOnRemove = true
    sound:Play()
    sound:Destroy()

    if receiptInfo.ProductId == skip then --SKIP STAGE
        player.leaderstats.Stage.Value = player.leaderstats.Stage.Value + 1
        player:LoadCharacter()
    else
        local tool = list[receiptInfo.ProductId] --TOOL
        tools:FindFirstChild(tool):Clone().Parent = player.Backpack
        tools:FindFirstChild(tool):Clone().Parent = player.StarterGear
    end

    return Enum.ProductPurchaseDecision.PurchaseGranted
end

MarketplaceService.ProcessReceipt = processReceipt

I think though the bug may be coming from my LocalScript? I have an ImageButton opening prompts yet however it's not working.

local player = game.Players.LocalPlayer
local ScreenGui = script.Parent
local ShopButton = ScreenGui:WaitForChild("ShopButton")
local ShopFrame = ScreenGui:WaitForChild("ShopFrame")
local SkipStageButton = ScreenGui:WaitForChild("SkipStageButton")
local UserInputService = game:GetService("UserInputService")


local MarketplaceService = game:GetService("MarketplaceService")
function promptProduct(productID)
    MarketplaceService:PromptProductPurchase(player, productID)
end

local DB = false
ShopButton.MouseButton1Down:Connect(function()
    if not DB then
        DB = true
        if ShopFrame.Visible then
            ShopFrame.Visible = false
        else
            ShopFrame.Visible = true
        end
        wait(0.5)
        DB = false
    end
end)

SkipStageButton.MouseButton1Down:Connect(function()
    promptProduct(1179259924)
end)

--[SHOP FRAME]
for i,v in pairs(ShopFrame:GetDescendants()) do
    if v:IsA("ImageButton") then
        v.MouseButton1Down:Connect(function()
            promptProduct(tonumber(v.Name))
        end)
    end
end

--[HOVER SOUND EFFECT]
for i,v in pairs(ScreenGui:GetDescendants()) do
    if v:IsA("ImageButton") then
        v.MouseEnter:Connect(function()
            local sound = Instance.new("Sound", player)
            sound.SoundId = "rbxassetid://408524543"
            sound.PlayOnRemove = true
            sound:Play()
            sound:Destroy()
        end)
    end
end

--[REPOSITION FOR MOBILE]
if UserInputService.TouchEnabled then
    wait()
    ShopButton.Position = UDim2.new(0, 0,0.45, 0)
    SkipStageButton.Position = UDim2.new(0, 0,0.45, 0)
end
