Why is it that Humanoid:MoveTo() will not work for my script?

Hello, i am creating a script where when the humanoid is damaged, it walks to the closest player in range. But it isn't working, when everything is correct and where it should walk.

Script:

local runService = game:GetService("RunService")

local oldHealth = 75

local range = 40

local targetFollow

local initiate = 0

script.Parent.Enemy.Changed:Connect(function(plays)
    local hum = script.Parent.Enemy
    
    print(1)
    
    if hum.Health < oldHealth then
        print(2)
        
        oldHealth = hum.Health
        
        local target
        
        local mag = math.huge
        
        for i, v in pairs(game.Players:GetPlayers()) do
            local magnitude = (script.Parent.HumanoidRootPart.Position - v.Character.HumanoidRootPart.Position).Magnitude
            
            if magnitude < mag then
                mag = magnitude
                
                target = v.Character
            end
        end
        
        if target ~= nil then
            print(3)
            
            if mag < range then
                targetFollow = target
                
                initiate = initiate + 1
                
                print(4)
            else
                targetFollow = nil
            end
        else
            targetFollow = nil
        end
    else
        oldHealth = hum.Health
    end
end)

local oldInitate = 0

runService.Stepped:Connect(function(plays)
    if targetFollow ~= nil then
        if oldInitate ~= initiate then
            local magnitude = (script.Parent.HumanoidRootPart.Position - targetFollow.HumanoidRootPart.Position).Magnitude
            
            if magnitude < range then
                script.Parent.Enemy:MoveTo(targetFollow.HumanoidRootPart.Position, targetFollow.HumanoidRootPart)
                
                initiate = oldInitate
                
                print("e")
            else
                targetFollow = nil
            end
        end
    end
end)

script.Parent.Enemy:MoveTo(targetFollow.HumanoidRootPart.Position, targetFollow.HumanoidRootPart) is the important line

targetFollow is my player, wont work. Please help

You can go to humanoid and set WalkTo the part you want and make a script that move to block on a specified position ontouched.
