How to push players in FE?

I have a script inside a part that pushes players away when touched (one way door). When running in-game, nothing happens. Here is the code. Does FE affect how this works?

door = script.Parent

function onTouch(hit)
    if hit.Parent == nil then return end
    local h = hit.Parent:FindFirstChild("Humanoid")
    if h ~= nil then
        hit.Parent.HumanoidRootPart.Velocity=door.CFrame.lookVector * 150
    end
end
door.Touched:connect(onTouch)
