These scripts don't give any errors in game. What's the problem?

No errors or anything, works to some extent when tested in studio, but in game nothing happens.

---This is the Server script
game.ReplicatedStorage.ValueReturnBus.OnServerInvoke = getPose
game.ReplicatedStorage.PosingTransitor.OnServerEvent:Connect(function(plr, posing, newpose, rScript)
    print("firing")
    if posing then
        newpose:Stop()
        plr.Character.Head.Heart.Enabled = false
        plr.Character.Humanoid.WalkSpeed = 16
        posing = false
        plr.PlayerScripts.Poses.PoseOutput.Value = true
        print("stopped")
    else
        posing = true
        getPose(posing)
        local pose = math.random(1, 1)
        if pose == 1 then
            newpose = plr.Character.Humanoid:LoadAnimation(rScript.Koichi)
            newpose:Play()
