Missing JsonObjectWrapper.generated.h when packaging game

I have a Game consisting of a Primary Game Module and a few Game Modules. One Game Module is adding a public dependency on Json and JsonUtilities:

        PublicDependencyModuleNames.AddRange(new string] { 
            "Core", "CoreUObject", "Engine",
            "Networking", "Sockets",
            "Json", "JsonUtilities" });

I am able to compile and run my game from the Unreal Editor, but when I try to package the game the build fails with the following error:

I saw one comment about this in the Unreal Engine 4.8 preview thread, but no solution:

Is anyone else experiencing this issue?

Does anyone have a workaround for this issue?

Is there a problem with JsonUtilities in 4.8?

I removed my dependency on JsonUtilities and just use the Json module. The game will package now.
