"invalid argument #2 (Vector3 expected, got nil) " But, I can't seem to find the problem

#1

I’m trying to test a hitbox for a sword of mine but, for the past few minutes I keep getting the same error.
"ServerScriptService.SwordCombat.CombatHandler:56: invalid argument #2 (Vector3 expected, got nil) "

apparently the problem is this line

hitbox.CFrame = humrp.CFrame * CFrame.new(0,0,0) * handler.SwordHitboxes[sequence]
``` (Line 56 on the Module Script)
I've searched around Google and the Forums themselves and haven't found anything that could help with my problem.

Main Script

```lua
local rp = game:GetService("ReplicatedStorage")
local combat = rp:WaitForChild("SwordCombat")

local handler = require(script.CombatHandler)

combat.OnServerEvent:Connect(function(Player, sequence)
	local character = Player.Character
	local h = character.Humanoid
	local humrp = character.HumanoidRootPart
	
	local sword = character:FindFirstChild("Sword")
	if sword then
		local plrAnim, swordAnim, length = handler.getAnimation(h,sword.Controller, sequence)
		plrAnim:Play()
		swordAnim:Play()
		
		plrAnim:GetMarkerReachedSignal("Hit"):Connect(function()
			handler.Attack(Player,character,humrp,sequence)
		end)
		
		task.delay(length, function()
			combat:FireClient(Player)
			
		end)
	end
end)

Module Script

local Animations = script:WaitForChild("Animations")
local plr = Animations.plr
local swrd = Animations.Sword
local meshes = script.Meshes

local KeyProvider = game:GetService("KeyframeSequenceProvider")
local debris = game:GetService("Debris")


local handler = {
	plrAnims = {
		["L"] = plr.R6_Slash1,
		["LL"] = plr.R6_Slash2,
		["LLL"] = plr.R6_Slash3
	},
	
	SwordAnims = {
		["L"] = swrd.R6_Sword1,
		["LL"] = swrd.R6_Sword2,
		["LLL"] = swrd.R6_Sword3
	},
	SwordHitboxes = {
		["L"] =	CFrame.Angles(math.rad(45), 0, 0),
		["LL"] = CFrame.Angles(0, 0, 0),
		["LLL"] = CFrame.Angles(0, 0, 0)
	}
	
}

function handler.getAnimation(Humanoid,SwordAnimationController, sequence)
	local length = 0
	
	local keysuquence = KeyProvider:GetKeyframeSequenceAsync(handler.plrAnims[sequence].AnimationId)
	local keyframes = keysuquence:GetKeyframes()
	
	for i=1, #keyframes do
		local Time = keyframes[i].Time
		if Time > length then
			length = Time
		end
	end
	
	return Humanoid.Animator:LoadAnimation(handler.plrAnims[sequence]), SwordAnimationController.Animator:LoadAnimation(handler.SwordAnims[sequence]), length
end


function handler.Attack(Player,character,humrp,length,sequence)
	local folder = Instance.new("Folder")
	folder.Name = "SwordCombat"
	folder.Parent = workspace
	debris:AddItem(folder, .25)
	
	local hitbox = meshes.HitBox
	hitbox.Size = Vector3.new(0.424, 5.018, 0.228)
	hitbox.Transparency = 0
	hitbox.CFrame = humrp.CFrame * CFrame.new(0,0,0) * handler.SwordHitboxes[sequence]
	hitbox.Parent = folder
	
	local weld1 = Instance.new("ManualWeld")
	weld1.Name = "HitboxW"
	weld1.Part0 = hitbox
	weld1.Part1 = humrp
	weld1.C0 = weld1.Part0.CFrame:ToObjectSpace(weld1.Part1.CFrame)
	weld1.Parent = weld1.Part0
end

return handler

Maybe the problem lies in the fact that in the normal script you pass 4 arguments, but in the module script you require 1 more.

You pass:
Player, char, humrp, sequence

You require:
PLayer, char, humrp, length, sequence

In your module script, you require Player,character,humrp,length,sequence for the Attack function while in the main script, you only send Player,character,humrp,sequence.
