can anyone can fix this error it say: attempt to index nil with 'Clone' ?

This is the Code:

local status = game.ReplicatedStorage.Status
local maps = game.ReplicatedStorage.Maps:GetChildren()
while true do
    for i = 1,10 do
        status.Value = "Intermisson "..10-i
        wait(1)
    end
    
    local rand = math.random(1, #maps)

    local map = maps[rand]:Clone()
    map.Parent = workspace
    
    status.Value = "We'll be playing "..map.Name
    wait(4)
  
    local players = game.Players:GetChildren()
    for i = 1,#players do
       if players[i].Character ~= nil then
           local spawnLocation = math.random(1,#workspace.Teleports:GetChildren())
            players[i].Character:MoveTo(workspace.Teleports:GetChildren()[spawnLocation].Position)
            players[i].Character.Parent = workspace.Ingame
        end
    end

   local roundLength = 50
   local canWin  = true
   local roundType = ""

   if map:FindFirstChild("Obby") then
      roundType = "Obby"
      map.EndPart.Touched:Connect(function(hit)
      if hit.Parent:FindFirstChild("Humanoid") then
         canWin = false
         status.Value = hit.Parent.Name.." has won!"
      end
   end)
elseif map:FindFirstChild("Sword") then
      roundType = "Sword"

      local children = workspace.Ingame:GetChildren()
      for i = 1,#children do
      local tool = map:FindFirstChild("Tool"):Clone()
      tool.Parent = children[i]
      end
   end

   map:FindFirstChildWhichIsA("Tool"):Destroy()
   end

   repeat 
       roundLength = roundLength -1
       status.Value = "Time Left: "..roundLength 
       wait(1)
   until roundLength == 0 or canWin == false or #workspace.Ingame:GetChildren() == 0 or (workspace.Ingame:GetChildren() == 1 and roundType == "Sword")
   
   if workspace.Ingame:GetChildren() == 1 and roundType == "Sword" then
      status.Value = workspace.Ingame:FindFirstChildWhichIsA("Model").Name.. " has won!"
   end
   wait(3)
   map:Destroy()

   local players = game.Players:GetChildren()
   for i = 1,#players do 
     if players[i].Character ~= nil then
       players[i]:LoadCharacter()
       end
   end
end

It's because you have an extra end on line 49. Remove it and see if it works.
