Problem creating session with Playfab in Unreal 5

I have been trying to integrate Playfab Party into Unreal 5 using the plugins available on Github (Playfab marketplace plugin and Online Subsystem Flayfab Party and Multiplayer). I manage to get connection to Playfab using my Steam credentials but when I do a CreateSession, I get the following sequence of events

LogOnline: PLAYFAB: FOnlineSubsystemPlayFab::CreateAndConnectToPlayFabPartyNetwork()
LogOnline: Verbose: PLAYFAB: FOnlineSubsystemPlayFab::OnCreateNewNetworkCompleted
LogOnline: Verbose: PLAYFAB: CreateNewNetworkCompleted: SUCCESS

LogSockets: Warning: Unable to load SocketSubsystem module PlayFabSockets
LogOnline: Verbose: PLAYFAB: FOnlineSubsystemPlayFab::OnLeaveNetworkCompleted

Any idea what is failing here?

Obviously some problems with the SocketSubsystem, but I can't find what is the problem here.

Any progress on this? I have the same issue using 4.27. I have steam OSS set as native platform service and playfab as default platform service. After logging into playfab using steam credentials, and attempting to create a session, I get the same error above where it fails to load PlayFabSockets module.

Hey! Are you using the Lyra Starter Game or the CommonUser Plugin? If so I found a pretty annoying bug in the way the code is playing out. For me it was destroying my session after a player logged in, but in my system I have the player create a lobby with themselves as the owner. So I would successfully start a party and then it was already queued to be destroyed. I need to find a solution to avoid this. Not even sure I need the commonuser plugin to be honest since I'm creating my own plugin for this type of stuff

Running into the same issue as the OP. Glad to know i'm not alone thought I was doing something wrong.

I got the session to create successfully by removing PLAYFAB_SOCKET_SUBSYSTEM from this function but the session still destroys and I get the "Unable to load SocketSubsystem module playfab" warning in my logs

void FOnlineSessionPlayFab::OnCreatePartyEndpoint(bool bSuccess, uint16 EndpointID, bool bIsHosting)
{
   if (OSSPlayFab)
   {
      OSSPlayFab->ClearOnPartyEndpointCreatedDelegates(this);
   }

   if (bIsHosting)
   {
      //PLAYFAB_SOCKET_SUBSYSTEM
      ISocketSubsystem* PlayFabSocketSubsystem = ISocketSubsystem::Get();
      if (bSuccess && OSSPlayFab && PlayFabSocketSubsystem)
      {
         UE_LOG_ONLINE_SESSION(Verbose, TEXT("SocketSubsystem: %s"), *PlayFabSocketSubsystem->GetSocketAPIName());
         bool BindAll = false;
         TSharedRef<FInternetAddr> LocalIp = PlayFabSocketSubsystem->GetLocalHostAddr(*GLog, BindAll);
         if (LocalIp->IsValid())
         {
            FString NetworkIdStr = OSSPlayFab->NetworkId;
            FString NetworkDescriptorStr = OSSPlayFab->SerializeNetworkDescriptor(OSSPlayFab->NetworkDescriptor);
            FString HostConnectInfo = LocalIp->ToString(false);

            PendingCreateSessionInfo.SessionSettings.Set(SETTING_NETWORK_ID, NetworkIdStr, EOnlineDataAdvertisementType::ViaOnlineService);
            PendingCreateSessionInfo.SessionSettings.Set(SETTING_NETWORK_DESCRIPTOR, NetworkDescriptorStr, EOnlineDataAdvertisementType::ViaOnlineService);
            PendingCreateSessionInfo.SessionSettings.Set(SETTING_HOST_CONNECT_INFO, HostConnectInfo, EOnlineDataAdvertisementType::ViaOnlineService);

            PendingCreateSessionInfo.SessionSettings.bIsDedicated = IsRunningDedicatedServer();
         }
         else
         {
            UE_LOG_ONLINE_SESSION(Verbose, TEXT("FOnlineSessionPlayFab::OnCreatePartyEndpoint: LocalHostAddr was invalid"));
         }

         if (!(InternalCreateSession(*PendingCreateSessionInfo.PlayerId, PendingCreateSessionInfo.SessionName, PendingCreateSessionInfo.SessionSettings)))
         {
            OnCreateSessionCompleted(PendingCreateSessionInfo.SessionName, false);
         }
      }
      else
      {
         OnCreateSessionCompleted(PendingCreateSessionInfo.SessionName, false);
      }
   }
}

Commenting out this code in the Init function inside the OnlineSubsystemPlayFab.cpp file got rid of the error where the socket was not getting created

// TSharedPtr<IPlugin> SocketsPlugin = IPluginManager::Get().FindPlugin(TEXT("PlayFab"));
// if (!SocketsPlugin.IsValid() || (SocketsPlugin.IsValid() && !SocketsPlugin->IsEnabled()))
// {
   UE_LOG_ONLINE(Log, TEXT("Initializing PlayFabPartSocketSubsystem"));
   CreatePlayFabSocketSubsystem();
//}
