Hello. Greetings, I found a strange thing. When updating a document, if a field contains a Dictionary<GUID, *>, an exception occurs.

settings:

 BsonSerializer.TryRegisterSerializer(new GuidSerializer(BsonType.String));

public class Lib
{
    public Dictionary<Guid, GameLib> Games { get; set; } = [];
    public Dictionary<string, GameLib> GamesX { get; set; } = [];
}
  1. request with Dictionary<Guid, *> error:
var uu = Builders<Lib>.Update.Set(f => f.Games[gameId].Status, GameLibStatus.Backlog);

MongoDB.Driver.Linq.ExpressionNotSupportedException: Expression not supported: f.Games.get_Item(229341dc-7125-4093-b407-7092245c7d9b).

  1. But then use Dictionary<string, *> all work fine:
var uu = Builders<Lib>.Update.Set(f => f.GamesX[gameId.ToString()].Status, GameLibStatus.Backlog);
