Why is the Animation Id failing to load?

I tried making keybind animations. They work just fine aside the error:

AnimationId failed to load

or something.

Here's the script:

local rs = game:GetService("ReplicatedStorage")

local e1 = rs.Move1Play
local e2 = rs.Move2Play
local e3 = rs.Move3Play
local e4 = rs.Move4Play

local id1 = workspace.MoveId1 -- The value is 4951461649
local id2 = workspace.MoveId2 -- The value is 4951461649
local id3 = workspace.MoveId3 -- The value is 4946579253
local id4 = workspace.MoveId4 -- The value is 4946579253



do

local function play1(plr)

    local char = plr.Character or plr.CharacterAdded:Wait()
    local h = char:FindFirstChild("Humanoid")

    local anim = Instance.new("Animation")

    if id1.Value then
    anim.AnimationId = "http://www.roblox.com/asset/?id=" .. tostring(id1.Value)
    end

    local track = h:LoadAnimation(anim)
    track:Play()

    end

            e1.OnServerEvent:Connect(play1)

end


do

local function play2(plr)

    local char = plr.Character or plr.CharacterAdded:Wait()
    local h = char:FindFirstChild("Humanoid")

    local anim = Instance.new("Animation")

    if id2.Value then
    anim.AnimationId = "http://www.roblox.com/asset/?id=" .. tostring(id2.Value)
    end

    local track = h:LoadAnimation(anim)
    track:Play()

    end

        e2.OnServerEvent:Connect(play2)

end


do

local function play3(plr)

    local char = plr.Character or plr.CharacterAdded:Wait()
    local h = char:FindFirstChild("Humanoid")

    local anim = Instance.new("Animation")

    if id3.Value then
    anim.AnimationId = "http://www.roblox.com/asset/?id=" .. tostring(id3.Value)
    end

    local track = h:LoadAnimation(anim)
    track:Play()

    end

        e3.OnServerEvent:Connect(play3)

end


do

local function play4(plr)

    local char = plr.Character or plr.CharacterAdded:Wait()
    local h = char:FindFirstChild("Humanoid")

    local anim = Instance.new("Animation")

    if id4.Value then
    anim.AnimationId = "http://www.roblox.com/asset/?id=" .. tostring(id4.Value)
    end

    local track = h:LoadAnimation(anim)
    track:Play()

    end

        e4.OnServerEvent:Connect(play4)

end
