Infinite yield possible on HumanoidRootPart

[Raven_fortnite3 (Raven)]

Hello devforum.

I made a door script using a tutorial on the devforum and when I test it, I get this error :
Infinite yield possible on ‘Workspace.Raven_fortnite3:WaitForChild(“HunanoidRootPart”)’

I tried searching on devforum for someone that had the same issue and it didn’t work.

-- SERVICES --

local uis, cas = game:GetService("UserInputService"), game:GetService("ContextActionService")
local cs, ts = game:GetService("CollectionService"), game:GetService("TweenService")

-- PLAYER & GUI VARIABLES --

local character = script.Parent
local players = game:GetService("Players")
local client = players.LocalPlayer

local root = character:WaitForChild("HunanoidRootPart")
local clientGui = client:WaitForChild("PlayerGui")
local doorGui = client:WaitForChild("doorKick")

local box = doorGui:WaitForChild("box")
local button = box:WaitForChild("button")
local fill = box:WaitForChild("fill")

local kickEvent = game.ReplicatedStorage:WaitForChild("onKick")
local mouse = client:GetMouse()

-- TWEENS --

local ti = TweenInfo.new(12, Enum.EasingStyle.Sine, Enum.EasingDirection.Out)

local fillTween = ts:Create(fill, ti,{Position = UDim2.new(0.5, 0, 0.5, 0)})

local door

-- UserInputService --

uis.InputBegan:Connect(function(inp, gpe)
	
	if gpe then
		return
	end
	if (inp.KeyCode == Enum.KeyCode[button.Text]) then
		door = mouse.Target
		
		if not (door ~= nil) then return end
		if ((root.Position - door.Position).Magnitude > doorGui.MaxDistance) then return end
		
		if (cs:HasTag(door, "Door")) then
			print("Instance is a door")
			
			fillTween:Play()
		end
	end	
		
end)

I would appreciate any help. Thanks

You misspelled HumanoidRootPart.

Bit of an awkward moment.

Oh wow… Kinda embarrassing. Thanks for the help

It might have been a spelling mistake in the topic. But if you did not make a spelling mistake then consider switching WaitForChild() to FindFirstChild().

[DasKairo (Cairo)]

Not Exactly

WaitForChild actually waits until a certain item exists,
Which is why it gives the warning:

Infinite yield possible for...

FindFirstChild looks for the Item, if its not found, it will return nil and will error when used unless called upon again
