question

Here is the error I'm seeing:

Here is my code:

 FString UCustomSteamSubsystem::SteamAuthToken()
 {
     FString AuthToken;
     IOnlineSubsystem* OnlineSubsystem = IOnlineSubsystem::Get();
     if (OnlineSubsystem)
     {
         IOnlineIdentityPtr IdentityInterface = OnlineSubsystem->GetIdentityInterface();
         if (IdentityInterface.IsValid())
         {
              AuthToken = IdentityInterface->GetAuthToken(0);
         }
     }
     return AuthToken;
  }
