How should I add offset on waypoints of pathfinding service?

I am making a game that I need the enemy to chase a player if they were attacked, but the pathfinding service is really wonky for me and I need help.

I needed for the enemy to not go "inside" of the player, but be on a range / offset so it will be more realistic.

I tried adding offset like this in every waypoint that was generated by the pathfinding service:

-- HumRoot = humanoidrootpart of the enemy that is chasing
-- Humanoid = humanoid of the enemy that is chasing
-- destination = position of the player's humanoidrootpart who attacked
local range = 5 -- studs on how much distance should the enemy be to start attacking

while not destinationReached do
	path:ComputeAsync(HumRoot.Position, destination)
	
	for _, waypoint in pairs(waypoints) do
		local offset = (HumRoot.Position - waypoint.Position).Unit*range
		Humanoid:MoveTo(waypoint.Position + offset) 
		Humanoid.MoveToFinished:Wait()
	end

	--removed some code about computing if destination is reached
end

the problem to this is, the enemy always look back / move back a step or two before reaching the destination, and sometimes they just stop. It commonly stops when there's an obstacle tho.

Any help is appreciated! Thank you!

I finally found a solution. What I did is put an if conditional in the waypoints array for loop:

--waypoint_dist is the calculated distance/magnitude between waypoint position and destination
for _, waypoint in pairs(waypoints) do
	if(waypoint_dist < range) then
		local offset = (HumRoot.Position - waypoint.Position).Unit * range
		local diff = destination + offset
		Humanoid:WalkTo(diff * Vector3.new(1,HumRoot.Position.y/diff.y,1))
		break
	else
		Humanoid:WalkTo(waypoint.Position)
	end
end

It doesn't exactly answer my question, but it did the same thing that I wanted to do. Hopefully someone will find this helpful too.
