How to fix gear spawners? It only works on one map

[NaturalPlants]

Hello, I want to know what is wrong with the script. Why do spawners work only on one map, and the code throws an error on other maps

Here is some paths:

Here is the code:

local RS = game:GetService("ReplicatedStorage")
local GearFolder = RS:WaitForChild("Gears"):GetChildren()

local MapHolder = RS:WaitForChild("MapHolder")

function chooseSpawn()
for i,v in pairs(MapHolder:GetChildren()) do
		local FindMapinWorkspace = game.Workspace:FindFirstChild(v.Name)
		local spawns = FindMapinWorkspace.SpawnFolder:GetChildren()
		if spawns  then		
		local _Spawn = spawns[math.random(1,#spawns)]

		return _Spawn	
		end
	end
end

local function chooseItem ()
	local item = GearFolder[math.random(1,#GearFolder)]

	return item
end

while task.wait(5) do
	local _spawn = chooseSpawn()
	local item = chooseItem()
	local clone = item:Clone()

	clone.Parent = game.Workspace
	clone.Handle.CFrame = _spawn.CFrame * CFrame.new(0,5,0)
end
