attempt to index nil with 'CFrame' - lua

Question

i was trying to make random spawns but sometimes, it gives me an error attempt to index nil with 'CFrame' when i enter the portal.
Here is the code
script.Parent.Touched:Connect(function(hit)
if hit.Parent:FindFirstChild('Humanoid') and not db and not hit.Parent.Parent:IsA("Tool") then
db = true
local spawns = workspace.Spawns
local spawnPoint = math.random(1,13)
local plr = game:GetService("Players"):GetPlayerFromCharacter(hit.Parent)
local ss = game:GetService("ServerStorage")
plr.InLobby.Value = false
if UIS.TouchEnabled == true then
script.Ability:Clone().Parent = plr.PlayerGui
end
if not plr.Backpack:FindFirstChild(plr.leaderstats.Glove.Value) and plr.leaderstats.Glove.Value ~= "edgelord" or plr.leaderstats.Glove.Value ~= "ḇ̵̰̪̙̭̎̓o̴̰͈͊̈̓̓̕b̶̨̀͐͌͑͒" then
if ss:FindFirstChild(plr.leaderstats.Glove.Value) then
ss:FindFirstChild(plr.leaderstats.Glove.Value):Clone().Parent = plr.Backpack
hit.Parent.HumanoidRootPart.CFrame = spawns:FindFirstChild(spawnPoint).CFrame
wait(2)
db = false
end
end
end
end)

The "attempt to index nil" error is always telling you that the object you're trying to get a value out of doesn't exist.
In this case, it's probably spawns:FindFirstChild(spawnPoint) that doesn't exist. The FindFirstChild searches the names of the children, and you are passing in a number between 1 - 13. This makes an assumption about the names of the children that is unnecessary and is likely the source of your error.
A safer way to access these objects is to simply get all of the spawn points as an array, and then access a random index within that array.
local spawns = workspace.Spawns:GetChildren()
local randomIndex = math.random(1, #spawns)
local targetCFrame = spawns[randomIndex].CFrame
hit.Parent.HumanoidRootPart.CFrame = targetCFrame
