What is wrong with my script? I tried using the PathfindingService.

i was watching a tutorial and i tried the script and it didnt work

and yes, i did double check to make sure that i was following the tutorial right

local PathfindingService = game:GetService("PathfindingService")

local human = script.Parent:WaitForChild("Humanoid")
local torso = script.Parent:WaitForChild("Torso")

local path = PathfindingService:CreatePath()
path:ComputeAsync(torso.Position, game.Workspace.endingPart.Position)
local waypoints = path:GetWaypoints()

for i, waypoint in pairs(waypoints) do
    human:MoveTo(waypoint.Position)
    human.MoveToFinished:Wait(2)
end

human:MoveTo(workspace.endingPart.Position)
