如图，
启动服务器，注册新账号，然后登陆，再获取用户的基本信息，是正常的。
接下来，重启服务端，然后登陆刚才注册的账号，成功，但是接下来的获取玩家基本信息出现Rpc错误信息。
刚开始学，研究了几天没弄明白，希望有知道的帮忙解惑，下面是具体的的错误信息：

玩家数据类如下：

namespace ETHotfix
{
    [BsonIgnoreExtraElements]
    public class PlayerInfo : Entity
    {
        private string playerName;

        public string PlayerName { get => playerName; set => playerName = value; }
    }
}

请求玩家数据：
G2C_PlayerInfo g2CPlayerInfo = (G2C_PlayerInfo)await Game.Scene.GetComponent<SessionComponent>().Session.Call(new C2G_PlayerInfo() { PlayerID = ETModel.Game.Scene.GetComponent<PlayerComponent>().MyPlayer.Id });

服务端获取玩家信息处理：

namespace ETHotfix
{
    [MessageHandler(AppType.Gate)]
    public class C2G_PlayerInfoHandler : AMRpcHandler<C2G_PlayerInfo, G2C_PlayerInfo>
    {
        protected override async ETTask Run(Session session, C2G_PlayerInfo request, G2C_PlayerInfo response, Action reply)
        {
            DBProxyComponent dbProxyComponent = Game.Scene.GetComponent<DBProxyComponent>();
            PlayerInfo playerInfo = await dbProxyComponent.Query<PlayerInfo>(request.PlayerID);
            response.PlayerName = playerInfo.PlayerName;
            reply();
        }
    }
}

如下处理却不会出现错误：
namespace ETHotfix
{
    [MessageHandler(AppType.Gate)]
    public class C2G_PlayerInfoHandler : AMRpcHandler<C2G_PlayerInfo, G2C_PlayerInfo>
    {
        protected override async ETTask Run(Session session, C2G_PlayerInfo request, G2C_PlayerInfo response, Action reply)
        {
            DBProxyComponent dbProxyComponent = Game.Scene.GetComponent<DBProxyComponent>();

            List<ComponentWithId> results = await dbProxyComponent.Query<PlayerInfo>(x => x.Id == request.PlayerID);
            Log.Info(MongoHelper.ToJson(results));

            PlayerInfo player = await dbProxyComponent.Query<PlayerInfo>(request.PlayerID);
            response.PlayerName = playerInfo.PlayerName;
            Log.Info(MongoHelper.ToJson(player));

            reply();
        }
    }
}
