How can I delete old path

Am making NPC that following moving item
if items’s position is changed
create new path for it
But NPC is following old path first,

How can I delete old path?

local PathfindingService = game:GetService("PathfindingService")

local Dummy = game.Workspace.Dummy
local humanoid = Dummy.Humanoid
local destination = game.Workspace.eeee

local pos = destination.Position

local path = PathfindingService:CreatePath()

path:ComputeAsync(Dummy.HumanoidRootPart.Position, pos)
local waypoints = path:GetWaypoints()

while true do 
if pos ~= destination.Position then
	pos = destination.Position
	print("target moved")
	local path = PathfindingService:CreatePath() ---Make new path
	path:ComputeAsync(Dummy.HumanoidRootPart.Position, pos)
	local waypoint = path:GetWaypoints() 
	end


for _, waypoints in pairs(waypoints) do
	local part = Instance.new("Part")
	
	if waypoints.Action == Enum.PathWaypointAction.Jump then
		humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
	end
	
	humanoid:MoveTo(waypoints.Position)
	humanoid.MoveToFinished:Wait()

end
end

At each step in for _ waypoints, I check to see if the Target has moved and break the for loop if it has. This forces the while true loop to recalculate the path.

How can I stop for loop?
“Break” is stopping white loop too

Move the waypoint navigation out of the while true loop and place it into a separate function. Call this function after path has been computed:

local function waypointMove()	-- Added function for waypoint navigation
	for _, waypoints in pairs(waypoints) do
-- Recalulate Target Position here. If moved then break		
		if pos ~= destination.Position then
				return
			end
		end		
		local part = Instance.new("Part")
		if waypoints.Action == Enum.PathWaypointAction.Jump then
			humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
		end
		humanoid:MoveTo(waypoints.Position)
		humanoid.MoveToFinished:Wait()
	end
end

while true do 
	if pos ~= destination.Position then
		pos = destination.Position
		print("target moved")
		local path = PathfindingService:CreatePath() ---Make new path
		path:ComputeAsync(Dummy.HumanoidRootPart.Position, pos)
		waypoints = path:GetWaypoints() 
	end
-- Call waypointMove function	
	waypointMove()
end
