How to update nested collection

[Jimmys20]

Hello, I'm trying to update a nested collection using new List but the new items are concatenated with the already existing items. Is this supported by Redis and Redis.OM? Here is a small demo of what I'm trying to do. Am I doing something wrong?

[Document(StorageType = StorageType.Json, Prefixes = ["Player"])]
public class PlayerEntity
{
  [RedisIdField, Indexed] public string UniquePlayerId { get; set; }

  public IEnumerable<ReportItem> ReportItems { get; set; }
}

public class ReportItem
{
  public string Caption { get; set; }
  public double Value { get; set; }
}

internal class Program
{
  static async Task Main(string[] args)
  {
    var redisConfigurationOptions = new StackExchange.Redis.ConfigurationOptions
    {
      EndPoints = { "192.168.100.4:6379" },
      User = null,
      Password = null,
      AllowAdmin = false,
      Ssl = false,
    };

    var provider = new RedisConnectionProvider(redisConfigurationOptions);

    provider.Connection.DropIndexAndAssociatedRecords(typeof(PlayerEntity));
    await provider.Connection.CreateIndexAsync(typeof(PlayerEntity));

    var players = provider.RedisCollection<PlayerEntity>();

    await players.InsertAsync(new PlayerEntity
    {
      UniquePlayerId = "some-unique-id",
      ReportItems = new List<ReportItem>
      {
        new ReportItem { Caption = "Score", Value = 100 },
        new ReportItem { Caption = "Time Played", Value = 3600 }
      }
    });

    var player = await players.FirstOrDefaultAsync(p => p.UniquePlayerId == "some-unique-id");
    Console.WriteLine("Count: " + player.ReportItems.Count()); // Count: 2

    player.ReportItems = new List<ReportItem>
    {
      new ReportItem { Caption = "Score", Value = 200 },
      new ReportItem { Caption = "Time Played", Value = 7200 }
    };

    await players.UpdateAsync(player);

    var updatedPlayer = await players.FirstOrDefaultAsync(p => p.UniquePlayerId == "some-unique-id");
    Console.WriteLine("Updated Count: " + updatedPlayer.ReportItems.Count()); // Updated Count: 4
  }
}

For a quick and temporary solution, you can "set saveState to false".

so

var players = provider.RedisCollection<PlayerEntity>(false);
