My Lighting movement dont work and in the OutPut says Infinite Yield posibble how can i fix it?

local Tool = script.Parent
local repstore = game:WaitForChild("ReplicatedStorage")

bolt.Anchored = true

function ShootElectrode(from,too)
    lastpos = from
    local Step = 3
    local Off = 10
    local Range = 400

    local Distance = (from-too).magnitude

    for i = 0,Distance, Step do
        local from = lastpos
        local offset = Vector3.new(
            math.random(-Off,Off),

         math.random(-Off,Off)
                                )/10

    local too = from + - (from-too).unit*Step + offset



    local p = bolt:Clone()
    p.Parent = Folder
    p.Size = Vector3.new(p.Size.x,p.Size.y,(from-too).magnitude)
    p.CFrame = CFrame.new(from:Lerp(too,0.5),too)


    game.Debris:AddItem(p,0.2)
    lastpos = too



    end

end
