How do I fix this simple animation issue for a player?(I wrote an error from the console)

I will explain my script briefly. This script is normal script. It is located in the door. The door has a "Handle" with a click detector in it. This is not the point. Let's move on to the second part of the script. The script detects if the player is in the team. If so, the door stops. is de-anchored and the player has to play the animation, the problem is that the animation does not work.

To help you troubleshoot the problem, this is the only error underlined in yellow on the console. " ? Infinite yield possible on 'Workspace.KotyOceloty:WaitForChild("humanoid")' (x2) - Studio"

function Open(player)
    if player.Team == game.Teams["DOR Members"] then
        if opened == false then
            opened = true
            for i = 1, 10 do
                script.Parent:SetPrimaryPartCFrame(Hinge.CFrame*CFrame.Angles(0, math.rad(9), 0))
                wait()
            end
        else
            opened = false
            for i = 1, 10 do
                script.Parent:SetPrimaryPartCFrame(Hinge.CFrame*CFrame.Angles(0, math.rad(-9), 0))
                wait()
            end
        end
    end

    if player.Team == game.Teams.Interpol then
        local copy = game.ReplicatedStorage.Door:Clone()
        local remain = game.ReplicatedStorage.CopyDoor:Clone()
        --animation script start
        local animation = Instance.new("Animation")
        animation.AnimationId = "http://www.roblox.com/Asset?ID="..8293367949
        --here the console shows I have a problem.(down)
        local loadedAnimation = game.Workspace[player.Name].Humanoid:LoadAnimation(animation)
        game.Workspace["Fbi open up"]:Play()
        wait(2.011)
        loadedAnimation:Play()
        --play animation
        wait(0.5)
        script.Parent:Destroy()
        remain.Parent = game.Workspace
        remain.Anchored = false
        --makes door fall from upstairs and plays sound
        game.Workspace["Wood Breaking"]:Play()
    end

    end

if someone still does not understand, it has what interests me written in the script. I am asking for a quick answer.
