Invalid argument #1 (CFrame expected, got Vector3)

I am using this script below to create a laser using a Beam, and it keeps erroring and I don’t know why. I am pretty new to raycasts so I’m not sure what I’m doing wrong.

local laserThickness = .1
local castLength = 500

local beam = script.Parent.Beam
local startatt = script.Parent.StartAttachment
local endatt = script.Parent.EndAttachment

local params = RaycastParams.new()
params.FilterDescendantsInstances = {}

game:GetService("RunService").Heartbeat:Connect(function()
	local laserLook = script.Parent.CFrame.LookVector
	local laserOrigin = startatt.Position

	local castResult = workspace:Raycast(laserOrigin,laserLook*castLength,params) or {Position = laserOrigin+laserLook*castLength,Distance = castLength}
	
	endatt.CFrame = CFrame.new(laserOrigin:Lerp(castResult.Position, .5, castResult.Position) * CFrame.Angles(0, math.pi/2,0))
		
end)
#2

just do CFrame.new(laserOrigin) instead of laserOrigin

#3

And where would I insert that in the script?

#4

at local castResult
charssssss

#5

It just says Unable to cast CoordinateFrame to Vector3 now as an error.

#6

try changing local laserOrigin = startatt.Position to local laserOrigin = startatt.CFrame

#7

You placed an end bracket in the wrong place:

endatt.CFrame = CFrame.new(laserOrigin:Lerp(castResult.Position, .5, castResult.Position)) * CFrame.Angles(0, math.pi/2,0)
