The parent property of ____ is locked,current parent: NULL, new parent Workspace

#1

I wanted to make randomly generating tiles,with the spawn and the exit only generating one time,but when i try running the generation i get an error saying:

“The Parent property of Spawn/Exit is locked, current parent: NULL, new parent Workspace”

How can i fix that?

Heres the script:

local Placeholders = game.Workspace.PlaceHolders
local rooms = game:GetService("ReplicatedStorage"):WaitForChild("Setpieces"):GetChildren()
local HasSpawn = false
local HasExit = false
task.wait(5)
for i, placeHolder in pairs(Placeholders:GetChildren()) do
	local chosenroom = rooms[math.random(1,#rooms)]:Clone()
	if chosenroom.Name == "Spawn" then -- Spawn
		if HasSpawn == false then
			HasSpawn = true
			chosenroom.PrimaryPart = chosenroom:WaitForChild("Carpet")
			chosenroom:SetPrimaryPartCFrame(placeHolder.CFrame)
		else
			chosenroom:Destroy()
			repeat 	
				local chosenroom = rooms[math.random(1,#rooms)]:Clone()
				if chosenroom.Name == "Spawn" then
					chosenroom:Destroy()
				end
			until chosenroom.Name ~= "Spawn"

		end
	elseif chosenroom.Name == "Exit" then -- Exit
		if HasExit == false then
			HasExit = true
			chosenroom.PrimaryPart = chosenroom:WaitForChild("Carpet")
			chosenroom:SetPrimaryPartCFrame(placeHolder.CFrame)
		else
			chosenroom:Destroy()
			repeat 	
				local chosenroom = rooms[math.random(1,#rooms)]:Clone()
				if chosenroom.Name == "Exit" then
					chosenroom:Destroy()
				end
			until chosenroom.Name ~= "Exit"

		end
	else -- Normal room
		chosenroom.PrimaryPart = chosenroom:WaitForChild("Carpet")
		chosenroom:SetPrimaryPartCFrame(placeHolder.CFrame)
		
	end


	
	
	placeHolder:Destroy()
	chosenroom.Parent = workspace -- Error here
end

Try this instead, you accidentally made a new variable instead of setting the value of a previous one:

--//Services
local ReplicatedStorage = game:GetService("ReplicatedStorage")

--//Variables
local Rooms = ReplicatedStorage.Setpieces:GetChildren()
local Placeholders = workspace.PlaceHolders

--//Controls
local HasSpawn = false
local HasExit = false

--//Initialization
task.wait(5)

for i, placeHolder in pairs(Placeholders:GetChildren()) do
	local chosenroom = Rooms[Random.new():NextInteger(1, #Rooms)]:Clone()
	
	if chosenroom.Name == "Spawn" then -- Spawn
		if not HasSpawn then
			HasSpawn = true
			
			chosenroom.PrimaryPart = chosenroom:WaitForChild("Carpet")
			chosenroom:PivotTo(placeHolder.CFrame)
		else
			chosenroom:Destroy()
			
			repeat 	
				chosenroom = Rooms[Random.new():NextInteger(1, #Rooms)]:Clone()
				
				if chosenroom.Name == "Spawn" then
					chosenroom:Destroy()
				end
			until chosenroom.Name ~= "Spawn"

		end
	elseif chosenroom.Name == "Exit" then -- Exit
		if not HasExit then
			HasExit = true
			
			chosenroom.PrimaryPart = chosenroom:WaitForChild("Carpet")
			chosenroom:PivotTo(placeHolder.CFrame)
		else
			chosenroom:Destroy()
			repeat 	
				chosenroom = Rooms[Random.new():NextInteger(1, #Rooms)]:Clone()
				
				if chosenroom.Name == "Exit" then
					chosenroom:Destroy()
				end
			until chosenroom.Name ~= "Exit"

		end
	else -- Normal room
		chosenroom.PrimaryPart = chosenroom:WaitForChild("Carpet")
		chosenroom:PivotTo(placeHolder.CFrame)
	end

	placeHolder:Destroy()
	
	if not chosenroom then
		warn("Chosen room could not be found.")
		
		return
	end
	
	chosenroom.Parent = workspace
end

Thank you,it works now but for some reason now some tiles dont spawn,guess its just another problem in my code
