What is causing the MarketplaceService to say it's "unable to cast value to object"?

local Lighting = game:GetService("Lighting")
local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")

local badgeId = "2124428647"
local toolNames = {"GhostBurger"}
local toolsParent = Lighting

local function onPlayerAdded(player)
    local function onCharacterAdded(character)
        if MarketplaceService:PlayerOwnsAsset(player.UserId, badgeId) then
            for i = 1, #toolNames do
                local tool = toolsParent:FindFirstChild(toolNames[i])
                if tool then
                    local clone = tool:Clone()
                    clone.Parent = player.Backpack
                end
            end
        end
    end

    if player.Character then
        onCharacterAdded(player.Character)
    end
    player.CharacterAdded:Connect(onCharacterAdded)
end

Players.PlayerAdded:Connect(onPlayerAdded)

It is line 11, where it lists the player.UserId, badgeId.
