why wont this work?

local p=game:GetService("PathfindingService")
p.EmptyCutoff=0
spawn(function()
	local torso,humanoid = script.Parent:WaitForChild("Torso"),script.Parent:WaitForChild("Humanoid")
	torso.Touched:connect(function()
		wait(math.random())
		humanoid.Jump = true
	end)
	local walk;
	walk=function()
		local target = script.Parent.Targe.Value.Torso
		local path=p:ComputeSmoothPathAsync(torso.Position,target.Position,500)
		if path.Status.Name == "Success" then
			local points = path:GetPointCoordinates()
			for i,point in pairs (points)do
				local part,P=workspace:FindPartOnRay(Ray.new(point,Vector3.new(0,-10,0)))
				if part then
					point = p
					points[i] = p
				end
			end
			local distance;
			for i=1,#points do
				local point = points[i]
				humanoid:MoveTo(point)
				local jump;
				if point.Y>=torso.Position.Y-1.5 then
					humanoid.Jump = true
					jump=humanoid.Changed:connect(function()
						humanoid.Jump = true
					end)
				end
				local reached=humanoid.MoveToFinished:wait()
				if jump then
					jump.Disconnect()
				end
				if not reached then
					return walk()
				end
			end
		else
			humanoid:MoveTo(torso.CFrame*Vector3.new(0,0,5))
			humanoid.MoveToFinish:wait()
		end
		return walk()
	end
	walk()
end)

it is a pathfind script. i use a different model to make my own but this does not work. in the output this error pops up. 00:30:36.619 - Unable to cast Instance to Vector3 00:30:36.619 - Script 'Workspace.Police.Script', Line 25 - local walk 00:30:36.619 - Script 'Workspace.Police.Script', Line 47 00:30:36.620 - Stack End can someone help me please
