Why does it say its unable to cast value to object?

SCRIPT IN STARTERPLAYERSCRIPTS

local Player = game:GetService("Players").LocalPlayer
local PlayAnimation = game.ReplicatedStorage.PlayAnimation --It states that its "unable to cast value to object"
local StopAnimation = game.ReplicatedStorage.StopAnimation
local Debounce = false
function onKeyPress(actionName, userInputState, inputObject)
    if userInputState == Enum.UserInputState.Begin then
        PlayEmote()
    end
end

function PlayEmote()
    if Debounce == false then
        PlayAnimation:FireServer(2471625994)
    else
        StopAnimation()
    end
end

game.ContextActionService:BindAction("keyPress", onKeyPress, false, Enum.KeyCode.E)

SCRIPT IN SERVERSCRIPTSERVICE

game.ReplicatedStorage.PlayAnimation.OnServerEvent:Connect(function(Player,Animation)
    local Anim = game.Workspace[Player.Name].Humanoid:LoadAnimation(Animation)
    Anim:Play()
    game.ReplicatedStorage.StopAnimation.OnServerEvent:Connect(function(Player)
        Anim:Stop()
    end)
end)

HOW IT WORKS: Basically, it's supposed to load an animation when you press E on the keyboard.
