How can I make a zombie go to the player with Humanoid:MoveTo() ?

I was following with a tutorial from TheDevKing on Magnitude. Here is the code:

local ZombieRoot = script.Parent.HumanoidRootPart
local ZombieHumanoid = script.Parent.Humanoid

local function findTarget()
    local agroDistance = 100
    for i, v in pairs(game.Workspace:GetChildren()) do
        local Root = v:FindFirstChild("HumanoidRootPart")
        local Humanoid = v:FindFirstChild("Humanoid")

        if Root and Humanoid and v ~= nil then
            if (ZombieRoot.Position - Root.Position).Magnitude < agroDistance then
                target = v
            end
        end
    end
    return target
end

while wait(1) do
    local Target = findTarget()

    if Target ~= nil then
        print("Found Target!")
        ZombieHumanoid:MoveTo(target.HumanoidRootPart.Position)
    end
end

There are no errors, but for some reason the zombie does not move to the target.

I also put two characters right beside the zombie to see if it would run the print function and it did but for some reason it did not move to the character.

I'm not sure if something else in my script is wrong or I used the Humanoid:MoveTo() function incorrectly. Please help me out if you what's wrong with my script. Thanks!
