The Pathfinding service is not working on a terrain?

Hey there, I got a basic pathfinding script for a character in my game. It worked when the character and the destination are on the baseplate, but not on a terrain. The character is not anchored.

local PathfindingService = game:GetService("PathfindingService")
 
local zombie = script.Parent
local humanoid = zombie.Humanoid
local destination = game.Workspace.dest
 
local path = PathfindingService:CreatePath()
path:ComputeAsync(zombie.HumanoidRootPart.Position, destination.Position)
humanoid:MoveTo(destination.Position)
 

Does anyone have a solution?

Problem is that you are not actually doing pathfinding your script. You do Compute path but you don't use it, later on, you just use MoveTo to the final destination and that's not how it's supposed to be. As it's explained step by step and there is example on Roblox Dev Hub you should follow it to fix and adapt your script:
