1523388494&serverplaceid=0" failed to load in "Animation.AnimationId": Animation failed to load?

Hi Im trying to make a punch script well the thing is that when I tried the script it doesnt work and the output gave me this error: Animation "https://www.roblox.com//asset/?id=1523388494&serverplaceid=0" failed to load in "Animation.AnimationId": Animation failed to load I have tried to change the animation but still doesnt work ill let the script down here

This is the play script:

local UserInputService = game:GetService("UserInputService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local punchEvent = ReplicatedStorage:WaitForChild("PunchEvent")

local ready = true

local function punch(inputObject, gameProcessed)
    if inputObject.KeyCode == Enum.KeyCode.Q and ready then
        punchEvent:FireServer()
        ready = false
        wait(0.5)
        ready = true
    end
end

UserInputService.InputBegan:Connect(punch)

and this is the anim script:

math.randomseed(tick())

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local punchEvent = Instance.new("RemoteEvent", ReplicatedStorage)
punchEvent.Name = "PunchEvent"

local animations = {1523385059, 1523388494}

local function onPunchFired(plr)
    local char = game.Workspace:FindFirstChild(plr.Name)
    local humanoid = char.Humanoid
    local animation = Instance.new("Animation")
    local picked = math.random(1, #animations)
    animation.AnimationId = "http://roblox.com/asset/?id="..animations[picked]
    local animTrack = humanoid:LoadAnimation(animation)
    animTrack:Play()
    local dmgScript = script.DmgScript:Clone()
    if picked == 1 then
        dmgScript.Parent = char.RightHand
    elseif picked == 2 then
        dmgScript.Parent = char.LeftHand
    end
    dmgScript.Disabled = false
    wait(0.4)
    dmgScript:Destroy()
end

punchEvent.OnServerEvent:Connect(onPunchFired)
