Empty fields which one of None

[dura0ok]

Summary

simple structs not parsing

Reproduction Steps

@dataclass class GameMessage(betterproto.Message): """Общий формат любого UDP-сообщения"""

msg_seq: int = betterproto.int64_field(1)
sender_id: int = betterproto.int32_field(10)
receiver_id: int = betterproto.int32_field(11)
ping: "GameMessagePingMsg" = betterproto.message_field(2, group="Type")
steer: "GameMessageSteerMsg" = betterproto.message_field(3, group="Type")
ack: "GameMessageAckMsg" = betterproto.message_field(4, group="Type")
state: "GameMessageStateMsg" = betterproto.message_field(5, group="Type")
announcement: "GameMessageAnnouncementMsg" = betterproto.message_field(
    6, group="Type"
)
join: "GameMessageJoinMsg" = betterproto.message_field(7, group="Type")
error: "GameMessageErrorMsg" = betterproto.message_field(8, group="Type")
role_change: "GameMessageRoleChangeMsg" = betterproto.message_field(9, group="Type")
discover: "GameMessageDiscoverMsg" = betterproto.message_field(12, group="Type")

@dataclass class GameMessageAckMsg(betterproto.Message): pass

msg = GameMessage(ack=GameMessageAckMsg(), sender_id=3) serialized = bytes(msg) deserialized = GameMessage().parse(serialized) print(betterproto.which_one_of(deserialized, "Type"))

Expected Results

(''ack", None)

Actual Results

('', None)
