Question [Lobby]: ValidationError, (16000). Message: request failed validation

Hi, I get this error when I tried to create lobby.

Problem occurs like this.

-I simply initialize services then in SignIn callback I create lobby. It creates lobby without problem.
-Then I exit playmode. It disposes lobby and removes all players bind to that lobby.
-On second time I enter play mode and repeat first step, I get error at LobbyService.Instance.CreateLobbyAsync();

Here's my Authentication Code.

Code (CSharp):

1.         private static async Task<bool> TryInitServicesAsync(string profileName = null)
2.         {
3.             if (UnityServices.State == ServicesInitializationState.Initialized)
4.                 return true;
5.  
6.             //Another Service is mid-initialization:
7.             if (UnityServices.State == ServicesInitializationState.Initializing)
8.             {
9.                 var task = WaitForInitialized();
10.                 if (await Task.WhenAny(task, Task.Delay(InitTimeout)) != task)
11.                     return false; // We timed out
12.  
13.                 return UnityServices.State == ServicesInitializationState.Initialized;
14.             }
15.  
16.             if (profileName != null)
17.             {
18.                 //ProfileNames can't contain non-alphanumeric characters
19.                 Regex rgx = new Regex("[^a-zA-Z0-9 - _]");
20.                 profileName = rgx.Replace(profileName, "");
21.                 var authProfile = new InitializationOptions().SetProfile($"{profileName}{LocalProfileTools.LocalProfileSuffix}");
22.  
23.                 //If you are using multiple unity services, make sure to initialize it only once before using your services.
24.                 await UnityServices.InitializeAsync(authProfile);
25.             }
26.             else
27.                 await UnityServices.InitializeAsync();
28.  
29.             return UnityServices.State == ServicesInitializationState.Initialized;
30.  
31.             async Task WaitForInitialized()
32.             {
33.                 while (UnityServices.State != ServicesInitializationState.Initialized)
34.                     await Task.Delay(100);
35.             }
36.         }
37.  
38.         public static async Task<bool> TrySignInAndCreateLobbyAsync(string profileName = null)
39.         {
40.             if (!await TryInitServicesAsync(profileName))
41.                 return false;
42.          
43.             Debug.Log("Unity service initialized");
44.          
45.             AuthenticationService.Instance.SignedIn += async () =>
46.             {
47.                 Debug.Log($"Signed in as {AuthenticationService.Instance.PlayerId}");
48.              
49.                 LobbyManager.Instance.InitializeLocalUser(AuthenticationService.Instance.PlayerId, profileName);
50.  
51.                 // Create the lobby
52.                 LobbyManager.Instance.CreateLobby($"{LobbyManager.Instance.LocalPlayer.DisplayName.Value}'s room.");
53.             };
54.             AuthenticationService.Instance.SignInFailed += (RequestFailedException e) =>
55.             {
56.                 GlobalMenuManager.Instance.FocusMenu(MenuEnum.AuthenticateMenu);
57.                 StringBuilder stringBuilder = new StringBuilder();
58.  
59.                 stringBuilder.Append("Reason: ");
60.                 stringBuilder.AppendLine(e.Source);
61.                 stringBuilder.Append("Message: ");
62.                 stringBuilder.AppendLine(e.Message);
63.                          
64.                 OutputHandler.Instance.ShowOneWayOutput($"Error {e.ErrorCode}", stringBuilder.ToString(), () =>
65.                 {
66.                     Debug.Log("Sign-in failed: " + e.Message);
67.                     TrySignInAndCreateLobbyAsync();
68.                 });
69.             };
70.          
71.             if (_isSigningIn)
72.             {
73.                 var task = WaitForSignedIn();
74.                 if (await Task.WhenAny(task, Task.Delay(InitTimeout)) != task)
75.                     return false; // We timed out
76.                 return AuthenticationService.Instance.IsSignedIn;
77.             }
78.  
79.             _isSigningIn = true;
80.             await AuthenticationService.Instance.SignInAnonymouslyAsync();
81.             _isSigningIn = false;
82.  
83.             return AuthenticationService.Instance.IsSignedIn;
84.  
85.             async Task WaitForSignedIn()
86.             {
87.                 while (!AuthenticationService.Instance.IsSignedIn)
88.                     await Task.Delay(100);
89.             }
90.         }

And Here's my LobbyManager

Code (CSharp):

1.         public void InitializeLocalUser(string playerId, string username)
2.         {
3.             _localPlayer.ID.Value = playerId;
4.             _localPlayer.DisplayName.Value = username;
5.         }
6.         public async Task<Lobby> CreateLobbyAsync(string lobbyName, int maxPlayers, bool isPrivate, LocalPlayer localUser)
7.         {
8.             if (_createCooldown.IsCoolingDown)
9.             {
10.                 Debug.LogWarning("Create lobby hit the rate limit.");
11.                 return null;
12.             }
13.              
14.             await _createCooldown.QueueUntilCooldown();
15.              
16.             CreateLobbyOptions createLobbyOptions = new CreateLobbyOptions()
17.             {
18.                 IsPrivate = isPrivate,
19.                 Player = CreatePlayer(localUser),
20.                 Data = new Dictionary<string, DataObject>()
21.                 {
22.                     { QueueTypeKey, new DataObject(DataObject.VisibilityOptions.Member, ((int)QueueType.Solo).ToString() ) }
23.                 }
24.             };
25.          
26.             _joinedLobby = await LobbyService.Instance.CreateLobbyAsync(lobbyName, maxPlayers, createLobbyOptions);
27.  
28.             StartHeartBeat();
29.  
30.             return _joinedLobby;
31.         }

I followed sample code comes with Lobby package so there is similarities.
