Your except block is throwing away the error message, which probably contains useful information. Try this instead: except Exception as ex:, and then print("error saving game: %s" % ex)

That error message seems to say that msg_obj does not contain a gameId. Try printing msg_obj before the Game.object.create() call.

@JohnGordon, gameId not here {'player1': 'han', 'player2': 'cat', 'winner': 'han', 'history': '[object History]', 'note': 'cat'} error saving game: 'gameId' and history not to convert to string

Okay then, the error is obvious -- your caller is not supplying a gameId argument. How you handle that error is up to you.
