NPC Pathfinding script isn't working as intended?

Hello! I decided to make really weird game because I was bored, and I want an npc to chase after you. I have code for it, except it is not working. No error is given. Here is the code:

function findNearestTorso(pos)
    local torso = nil
    local dist = 99999999999999999999999999999999999999999999999999999999999999999999999999
    local temp2 = nil
    local temp = nil
    local list = workspace:GetChildren()
    for x = 1, #list do
        temp2 = list[x]
        temp = temp2:FindFirstChild('Torso') or temp2:FindFirstChild('UpperTorso')
        if temp then
            if (temp.Position - pos).Magnitude < dist then
                torso = temp
                dist = (temp.Position - pos).Magnitude
            end
        end
    end
    return torso
end
local target = findNearestTorso(script.Parent.UpperTorso.Position)
local pfs  = game:GetService("PathfindingService")
    local path = pfs:CreatePath()
local waypoints = path:GetWaypoints()
path:ComputeAsync(script.Parent.UpperTorso.Position, target.Position)
for _, v in pairs(waypoints) do
    if v.Action == Enum.PathWaypointAction.Jump then
        script.Parent.Humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
    end
    script.Parent.Humanoid:MoveTo(v.Position)
    script.Parent.Humanoid.MoveToFinished:Wait(2)
    end
