Attempt to index nil with CFrame- Hitbox problem (Help)

Help and Feedback Scripting Support

So i was using a tutorial on how to make a grab skill in youtube and everything was going well until i started testing. The problem is that it attempts to index nil with CFrame in line 34 of the Module Script. I looked around other topics but they dont solve my issue.

Module Script:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Animations = ReplicatedStorage.Animations

local Handler = {}

Handler.playerDebounce = {}
Handler.hitboxLifeTime = .25
Handler.grabDuration = 1
Handler.tickRate = 10
Handler.damage = 1

Handler.confirmTarget = {}

Handler.coolDown = 1

function Handler.playAnimations(humanoid: Humanoid, typeOfAnim: string)
	local currentAnim
	
	if typeOfAnim == "User" then
		currentAnim = humanoid.Animator:LoadAnimation(Animations.GrabUser)
	elseif typeOfAnim == "Target" then
		currentAnim = humanoid.Animator:LoadAnimation(Animations.GrabTarget)
	end
	
	return currentAnim
end

function Handler.spawnHitbox(player, character, rootPart)
	local Folder = Instance.new("Folder")
	Folder.Name = "GrabMove"
	Folder.Parent = workspace
	
	local Hitbox = ReplicatedStorage.Hitbox:Clone()
	Hitbox.CFrame = rootPart.CFrame * CFrame.new(0, 0, -Hitbox.Size.Z) --Line 34 Heres the problem
	Hitbox.Parent = Folder
	
	local weld = Instance.new("Weld")
	weld.Part0 = Hitbox
	weld.Part1 = rootPart
	weld.C0 = weld.Part0.CFrame:ToObjectSpace(weld.Part1.CFrame)
	weld.Parent = weld.Part0
	
	local connection = Hitbox.Touched:Connect(function()end)
	
	local results = Hitbox:GetTouchingParts()
	
	coroutine.wrap(function()
		for i=1, #results do
			local obj = results[i]
			
			if not obj:IsDescendantOf(character) then
				local enemyHumanoid = obj.Parent:FindFirstChild("Humanoid")
				local enemyRoot = obj.Parent:FindFirstChild("HumanoidRootPart")
				
				if enemyHumanoid and enemyRoot and enemyHumanoid.Health > 0 then
					if Handler.confirmTarget[player.Name] then
						return
					end
					
					Handler.confirmTarget[player.Name] = true
					
					local newCframe = rootPart.CFrame * CFrame.new(0, 0, -4)
					local lookPosition = Vector3.new(rootPart.Position.X, enemyRoot.Position.Y, rootPart.Position.Z)
					
					enemyRoot.CFrame = CFrame.lookAt(newCframe.Position, lookPosition)
					
					local targetAnimation = Handler.playAnimations(enemyHumanoid, "Target")
					targetAnimation:Play()
					
					coroutine.wrap(function()
						local canTick = true
						task.delay(Handler.hitboxLifeTime, function()
							canTick = false
						end)
						
						while task.wait(.1) do
							if not canTick then
								break
							end
							
							enemyHumanoid:TakeDamage(Handler.damage)
							
							task.wait(Handler.grabDuration / Handler.tickRate)
						end
					end)()
					
					if Hitbox then
						Folder:Destroy()
					end
					
					if connection then
						connection:Disconnect()
					end
					
					return
				end
			end
		end
	end)()
	
	task.delay(Handler.hitboxLifeTime, function()
		if Hitbox then
			Folder:Destroy()
		end
		
		if connection then
			connection:Disconnect()
			
		end
	end)
	
end

return Handler

Server Script which is the parent of the Module Script it may help:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local GrabRemote = ReplicatedStorage:WaitForChild("Grab")

local Handler = require(script.Handler)

GrabRemote.OnServerEvent:Connect(function(player)
	local character = player.Character
	local humanoid = character.Humanoid
	local rootPart = character.HumanoidRootPart
	
	if Handler.playerDebounce[player.Name] then
		return
	end
	
	Handler.playerDebounce[player.Name] = true
	
	local userAnimation = Handler.playAnimations(humanoid, "User")
	userAnimation:Play()
	
	userAnimation:GetMarkerReachedSignal("Damage"):Connect(function()
		Handler.spawnHitbox(rootPart)
		
		task.delay(Handler.hitboxLifeTime, function()
			if not Handler.confirmTarget[player.Name] then
				userAnimation:Stop()

				task.delay(Handler.coolDown, function()
					if Handler.playerDebounce[player.Name] then
						Handler.playerDebounce[player.Name] = nil

					end

					if Handler.confirmTarget[player.Name] then
						Handler.confirmTarget[player.Name] = nil
					end
				end)

				GrabRemote:FireClient(player, Handler.coolDown)
			else
				task.delay(Handler.grabDuration, function()
					
					if Handler.playerDebounce[player.Name] then
						Handler.playerDebounce[player.Name] = nil
					end

					if Handler.confirmTarget[player.Name] then
						Handler.confirmTarget[player.Name] = nil
					end
					
					GrabRemote:FireClient(player, Handler.coolDown)
				end)	
			end
		end)
		
		Handler.spawnHitbox(player, character, rootPart)
	end)	
end)

Heres the Youtube video if it helps: https://www.youtube.com/watch?v=y4fpzKz-hiY

Have you tried using the built-in service called, “HitboxService?” The service provides a list of options in the order when called “CreateHitbox.” These options include:

1.CFrame
2.CFrame
3.Size
4.HitboxParams
5.Shape

When you do this as a local, you can get the hitboxes contents by looping through it.

for _,v in Hitbox do
-- Insert Internet Code Here.
end

I had never heard of it but i would like understanding what is the issue with my script and why is it working on the video and not in my game… Anyways thanks for the reply i will check the service right now to see if i can do something later with it.

I believe that service does not exist that might be an AI

It does look: Hitbox Service, easily create Accurate Hitboxes using minimal scripting!

Ah okay the same person has been flooding other forums with AI-generated stuff so I assumed
