Attempt to index nil with 'Lights'

Help and Feedback Scripting Support

Hey, I have an issue with my code, here is the error:
ServerScriptService.Server.Room:10: attempt to index nil with 'Lights' - Serveur - Room:10

Here is my Server script:

local room = require(script.Room)
local door = require(script.Room.Door)
local baconspirit = require(script.BaconSpirit)

local prevRoom = workspace.Entrance
local playerEnter = script.Room.PlayerEnter
local firstDoor = door.New(prevRoom, 1)

local generatedRooms = {prevRoom}

for i=2, 61 do
	prevRoom = room.Generate(prevRoom, i)
	generatedRooms[i] = prevRoom
end

playerEnter.Event:Connect(function(number)
	if number % math.random(2,10) == 0 then
		room.Blackout(generatedRooms[number])
		room.Blackout(generatedRooms[number+1])
		task.wait(2)
		baconspirit.New(number, generatedRooms)
	end
end)

Here is my Room script:

local door = require(script.Door)
local furniture = require(script.Furniture)

local room = {}
room.info = require(script.RoomInfo)
room.lastTurnDirection = nil
room.random = Random.new()

function room.Blackout(roomModel)
	local lamps = roomModel.Lights:GetChildren()
	for i, lamp in ipairs(lamps) do
		for i, obj in ipairs(lamp:GetChildren()) do
			if obj.Name == "Lights" then
				obj:Destroy()
			end
		end
	end
end

Thanks if you help me!

Is the model you send to the function only the model name, or is it the path to the model (workspace.Model for example)? If it’s only the name you’re sending, then that should be the problem. Else it might be a spelling error either in the script or inside of the roomModel, such as one having capital L and the other lower L.

This is the only potential issue I see, the function will error if the argument is nil.

It is the path that send to the function.
I check, and there is no spelling error in the script.

I found the problem, when I print:

print(generatedRooms[number])

It’s return nil.
Can you help me to found the value of number in the table generatedRooms?

If it’s a model or file with children, try this:

print(generatedRooms:GetChildren())

If it’s a table made in a script, try this:

print(generatedRooms)

If the printed result is an empty list, there are no values in generatedRooms, thus creating an error.
If this is the case, can you post the part of code that sends generatedRooms?

Hello, first of all, thank you all for helping me solve my problem.
I finally found a solution.
