Raycast sliding problems

Help and Feedback Scripting Support

Hello! Decently new scripter here. I’m trying to follow along with a tutorial that shows how to create a sliding system with RaycastHitboxV4, but I’ve gotten into a few hiccups.

  1. The hitboxes for the rays are not attaching to my character’s feet
  2. My slide animation isn’t loading when I hit Q (my keybind)
  3. Print statements are not printing in the output
  4. image I’m consistently getting this error when playtesting. It leads back to the script that creates Signals.

Here is my code. If anyone could help me I would be extremely thankful. I can also supply the code in my module scripts if need be.

OnSlide 
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local ContextActionService = game:GetService("ContextActionService")
local Promise = require(ReplicatedStorage.Modules.Promise)

local RaycastModule = require(ReplicatedStorage.Modules.RaycastHitboxV4)

local plr = game.Players.LocalPlayer
local playerConfig = require(plr.PlayerScripts:WaitForChild("PlayerModule"))
local ctrls = playerConfig:GetControls()
local char = script.parent
local hrp = char:WaitForChild("HumanoidRootPart")
local slideHitboxModel = plr.Backpack.SlideHitboxes

local slideHitbox = RaycastModule.new(slideHitboxModel)
slideHitbox.DetectionMode = RaycastModule.DetectionMode.PartMode
slideHitbox.Visualizer = true
slideHitbox.RayDirection = Vector3.new(0, -0.6, 0.3)

local params = RaycastParams.new()
params.FilterDescendantsInstances = {plr.Character}
params.FilterType = Enum.RaycastFilterType.Blacklist
params.IgnoreWater = true

slideHitbox.RaycastParams = params

local slidingAttachment = Instance.new("Attachment")

local slideAccel = 32

function onSlideKeyPressed(actionName, inputState, inputObject)
	if inputState == Enum.UserInputState.Begin then
		doSlide()
	end
end

ContextActionService:BindAction("SLIDE_ACTION", onSlideKeyPressed, true, Enum.KeyCode.Q)

				if timeSinceSlideStart >= 0.2 then

					end
				end
			end)
		end
		
	end)

	slideHitbox:HitStart()
	
	game:GetService("RunService").Heartbeat:Wait()

There error is in the Module Script it looks like.
