(ANSWERED)I tried to use ray cast, and it gave me an error, why?

I was testing out ray cast, and I made this script:

while wait(1) do
local ray = Ray.new(script.Parent.Position, Vector3.new(0,500,0))
local hit = game.Workspace:FindPartOnRayWithIgnoreList(ray, script.Parent) --HERE
print(hit)
end

and it gave me the error: Unable to cast value to Objects Someone please tell me how I can fix it. Any form of help is appreciated :-)
