question

Hello all, I am trying to create lobby. But I got error like "The list of members is empty". How can i fix it? Here is my code. I couldn't find any documention about creating lobby in unity.

public void CreateLobby() {

     var createRequest = new CreateLobbyRequest()
     { 
         MaxPlayers = 2,
        OwnerMigrationPolicy =  OwnerMigrationPolicy.None,
        Owner = new PlayFab.MultiplayerModels.EntityKey()
        {
            Type = _entityKey.Type,
            Id = _entityKey.Id
        },
        UseConnections = true,
     };

     PlayFabMultiplayerAPI.CreateLobby(createRequest,
         result => { message.text = "Created lobby";},
         OnError 
     );
        
        
 }
