Empty ProductUserID in Lobby

[MenesApps]

Hi,
I have an issue when trying to create a lobby. The click button function retuns this null exception :

NullReferenceException: Object reference not set to an instance of an object PlayEveryWare.EpicOnlineServices.Samples.EOSLobbyManager.CreateLobby (PlayEveryWare.EpicOnlineServices.Samples.Lobby lobbyProperties, PlayEveryWare.EpicOnlineServices.Samples.EOSLobbyManager+OnLobbyCallback CreateLobbyCompleted) (at Assets/Samples/Epic Online Services Plugin for Unity/2.1.7/EOS Plugin for Unity Samples/Scripts/EOSLobbyManager.cs:923) LobbyMenu.CreateNewLobbyButtonOnClick () (at Assets/Scripts/Menus/LobbyMenu.cs:235) UnityEngine.Events.InvokableCall.Invoke () (at <685c48cf8f0b48abb797275c046dda6a>:0) UnityEngine.Events.UnityEvent.Invoke () (at <685c48cf8f0b48abb797275c046dda6a>:0) UnityEngine.UI.Button.Press () (at Library/PackageCache/[email protected]/Runtime/UI/Core/Button.cs:70) UnityEngine.UI.Button.OnPointerClick (UnityEngine.EventSystems.PointerEventData eventData) (at Library/PackageCache/[email protected]/Runtime/UI/Core/Button.cs:114) UnityEngine.EventSystems.ExecuteEvents.Execute (UnityEngine.EventSystems.IPointerClickHandler handler, UnityEngine.EventSystems.BaseEventData eventData) (at Library/PackageCache/[email protected]/Runtime/EventSystem/ExecuteEvents.cs:57) UnityEngine.EventSystems.ExecuteEvents.Execute[T] (UnityEngine.GameObject target, UnityEngine.EventSystems.BaseEventData eventData, UnityEngine.EventSystems.ExecuteEvents+EventFunction1[T1] functor) (at Library/PackageCache/[email protected]/Runtime/EventSystem/ExecuteEvents.cs:272) UnityEngine.EventSystems.EventSystem:Update() (at Library/PackageCache/[email protected]/Runtime/EventSystem/EventSystem.cs:501)

When I navigate to the error, it shows that ProductUserId currentUserProductId = EOSManager.Instance.GetProductUserId(); returns a null value.
My config file is filled with the required values and the login code is successful. Am I doing something wrong or is this a bug? You'll find the login code below (using the Device ID login).

Thanks a lot.

Login Code

        createDeviceIdOptions.DeviceModel = deviceModel;
        EOSManager.Instance.eosPlatformInterface.GetConnectInterface().CreateDeviceId(ref createDeviceIdOptions, null, OnCreateDeviceId);

    };
    loginOptions.UserLoginInfo = uli;

    Credentials cd = new Credentials()
    {
        Token = null,
        Type = connectInterfaceCredentialType
    };
    loginOptions.Credentials = cd;
    EOSManager.Instance.eosPlatformInterface.GetConnectInterface().Login(ref loginOptions, null, OnConnectInterfaceLogin);
}

public bool ready;

{
    if (loginCallbackInfo.ResultCode == Result.Success)
    {
        Debug.Log("Connect Interface Login succeeded");            
        ready = true;

       /* var authExpirationOptions = new Epic.OnlineServices.Connect.AddNotifyAuthExpirationOptions();
        authExpirationHandle = EOSPlatform.GetConnectInterface().AddNotifyAuthExpiration(authExpirationOptions, null, OnAuthExpiration);*/

    }
    else if (Epic.OnlineServices.Common.IsOperationComplete(loginCallbackInfo.ResultCode))
    {
        //TBA

    }

Hello,
I believe what is happening is that you're using a custom login flow by directly calling the EOS Connect interface's Login method, which means the internal state of the EOSManager won't set the ProductUSerID correctly. If you call Login outside of the Login Methods provided by the EOSManager, you'll then have to manually manage most of the various IDs that the EOS SDK exports. Alternatively you can use the StartConnectLoginWithDeviceToken instead and that should resolve the Null ref exception you are seeing.

Thanks for the reply, I'll try this as soon as I am able and will come back with results.

It seems like this was the issue. Replaced my custom code by the StartConnectLoginWithDeviceToken and it appears to work.
Thanks a lot !

Could you please share the updated code?

Sorry, just saw your question. If it isn't too late, I simply call EOSManager.Instance.StartConnectLoginWithDeviceToken("testplayer", loginCallback);

And get this callback

public void loginCallback(Epic.OnlineServices.Connect.LoginCallbackInfo loginCallbackInfo)
    {
        if (loginCallbackInfo.ResultCode == Result.Success)
        {
            Debug.Log("Connect Interface Login succeeded");
            Debug.Log("EOSPlatform localUserProductId:" + loginCallbackInfo.LocalUserId);
            string localUserProductId = loginCallbackInfo.LocalUserId.ToString();
            localID = localUserProductId;
            ProductUserId currentUserProductId = EOSManager.Instance.GetProductUserId();
            Debug.Log("currentUserProductId = " + currentUserProductId);
            Debug.Log("localID:" + localID);
            ready = true;
        }
        else 
        {
            print("Error logging in. [" + loginCallbackInfo.ResultCode + "]");
        }
    }

Hope that helps.
