I did this so that when an npc touches you it turns you invisible but I get that error, what do I do?

script.Parent.Touched:Connect(function(hit)
	local humanoid = hit.Parent:FindFirstChild("Humanoid")
	local humanoidrootpart = hit.Parent:FindFirstChild("HumanoidRootPart")
	
	local LeftFoot = hit.Parent:FindFirstChild("LeftFoot")
	local LeftHand = hit.Parent:FindFirstChild("LeftHand")
	local LeftLowerArm = hit.Parent:FindFirstChild("LeftLowerArm")
	local LeftLowerLeg = hit.Parent:FindFirstChild("LeftLowerLeg")
	local LeftUpperArm = hit.Parent:FindFirstChild("LeftUpperArm")
	local LeftUpperLeg = hit.Parent:FindFirstChild("LeftUpperLeg")
	local LowerTorso = hit.Parent:FindFirstChild("LowerTorso")
	local RightFoot = hit.Parent:FindFirstChild("RightFoot")
	local RightHand = hit.Parent:FindFirstChild("RightHand")
	local RightLowerArm = hit.Parent:FindFirstChild("RightLowerArm")
	local RightLowerLeg = hit.Parent:FindFirstChild("RightLowerLeg")
	local RightUpperArm = hit.Parent:FindFirstChild("RightUpperArm")
	local RightUpperLeg = hit.Parent:FindFirstChild("RightUpperLeg")
	local UpperTorso = hit.Parent:FindFirstChild("UpperTorso")
	local Head = hit.Parent:FindFirstChild("Head")

	local p1 = tween:Create(LeftFoot,info,goal2)
	local p2 = tween:Create(LeftHand,info,goal2)

#2

the object is not loaded yet, then the FindFirstChild returns nil

or the toucher is not a rig
if you want to make sure it has a humanoid

if not humanoid then return end
#3

Replace all the FindFirstChild() with WaitForChild(). This would either yield for loading or return the part if it is already loaded.

#4

I get this error when I try with waitforchild
Infinite yield possible on ‘Workspace:WaitForChild(“PLAYER PART”)’

#5

it means it takes too long to load the object

#6

You must check whether it is touched by a player as Baseplate fires Touched event too. Just add this conditional gate:

if hit and hit.Parent and hit.Parent:FindFirstChild("Humanoid") then ```
