Slash Animation using AnimationController not playing the animation?

So there was a problem where the slash animation doesn't work, The AnimationController Is Inside of the tool and the Animator Is stored In the AnimationController which the animator stores the SlashAnimation

script:

local Tool = script.Parent
local AnimationController = Tool.AnimationController
local Animator = AnimationController.Animator
local Animation = Animator.SlashAnim
local AnimationTrack

Tool.Activated:Connect(function()
    AnimationTrack = AnimationController.Animator:LoadAnimation(Animation)
    AnimationTrack:Play()
end)
