Not ignoring designated part on FindPartOnRayWithIgnoreList()?

Now I have seen other similar questions on various sites, including this one, and I just can't seem to get this to work using the advice from anyone. All I'm trying to do is to get the ray to ignore the part that the ray has created. I have tried simply making the part itself ignored, adding folders, creating tables, etc. Nothing works. Any help is greatly appreciated and I sincerely apologize for asking a question more than once on the site, but I was unable to figure it out using the previous posts. Thank you.

local play = game.Players.LocalPlayer
local mouse = play:GetMouse()
local tool = script.Parent
local equipped = false
local fire = false

function Shoot(pos,laser)
	if fire == true then
	repeat
	wait()
	local folder = workspace.Folder
	local startCFrame  = tool.Handle.CFrame
	local normal = startCFrame.LookVector
	local position = startCFrame.Position
	local ray = Ray.new(position, normal * 500)
	local hit, position, surfaceNormal = workspace:FindPartOnRayWithIgnoreList(ray,{folder}) --problem is here
	laser.Size = Vector3.new(0.4, 0.4, (mouse.Hit.p - tool.Handle.Position).Magnitude)
	laser.CFrame = CFrame.new(tool.Handle.Position:Lerp(mouse.Hit.p, 0.5), mouse.Hit.p)
	until fire == false
	laser:remove()
	end
end

mouse.Button1Up:connect(function()
	fire = false
end)

mouse.Button1Down:connect(function()
	if equipped then
		fire = true
		local laser = Instance.new("Part")
		laser.Name = "Laser"
		laser.TopSurface = Enum.SurfaceType.Smooth
		laser.BottomSurface = Enum.SurfaceType.Smooth
		laser.Size = Vector3.new(0.2, 0.2, 0.2)
		laser.BrickColor = BrickColor.new("Bright red")
		laser.Anchored = true
		laser.CanCollide = false
		laser.Locked = true
		laser.CFrame = tool.Handle.CFrame
		laser.Parent = workspace.Folder
		Shoot(mouse.Hit.p,laser)
	end
end)

tool.Equipped:Connect(function()
	equipped = true
end)

tool.Unequipped:Connect(function()
	equipped = false
	fire = false
end)

When you are excluding things from the ray, they have to be objects and not a string value, number value, etc. They have to be the direct object.

In an array you can include things from workspace.

object list = {game.Workspace.Model, game.Workspace.Part}
workspace:FindPartOnArrayWithIgnoreList(ray, objectList) 

Just make sure you include the EXACT OBJECT and not a name for it.

If you have any questions or issues please contact me. ;)
