How Do I Fix "Infinite yield possible on 'Workspace:WaitForChild("Spawn")"?

Heres My Script

local status = game.ReplicatedStorage:WaitForChild("Status")
local players = game.Players:GetChildren()
local maps = game.Lighting.Maps:GetChildren()
local currentmap = game.Workspace:WaitForChild("CurrentMap")
local chosenmap = script:WaitForChild("ChosenMap")
local spawner = game.Workspace:WaitForChild("Spawn")
local choices = {}

--Choose a random map
function choosemap()
  for i = 1,#maps do
 if maps[i]:isA("Model")then
  table.insert(choices,maps[i])
 end
end
local picked = math.random(1,#maps)
chosenmap.Value = choices[picked].Name
end

--Load the map
function loadMap()
 local map = game.Lighting.Maps:FindFirstChild(chosenmap.Value)
 map:Clone().Parent = currentmap
end

--Delete the map
function deleteMap()
 for i,v in pairs(currentmap:GetChildren())do
  if v:isA("Model") then
   v:Destroy()
  end
 end
end

--Teleport all the players
function teleportPlayers()
 for i,v in pairs(players)do
  v.Character.HumanoidRootPart.CFrame = currentmap:FindFirstChild(chosenmap.Value).Spawn.CFrame * CFrame.new(math.random(5,10),0,math.random(5,10))
  end
end

--Teleport back the players
function teleportBack()
 for i,v in pairs(players)do
  v.Character.HumanoidRootPart.CFrame = spawner.SpawnLocation.CFrame * CFrame.new(math.random(5,10),0,math.random(5,10))
 end
end

--The whole cycle
while true do
        status.Value = "Choosing Map..."
wait(3)
    choosemap()
    status.Value = "Chosen Map: "..chosenmap.Value
    loadMap()
wait(2)
    status.Value = "Teleporting Players.."
wait(5)
    teleportPlayers()
wait(60)
    deleteMap()
    teleportBack()
end
