An item with the same key has already been added

Hi guys,

I'm just load testing the API to see how fast we can read and write documents with OM library.

I've create a Model like:

[Document(IndexName = "aggregations-idx", StorageType = StorageType.Json, Prefixes = [CacheKeysOptions.Aggregations])]
public sealed class Aggregation
{
    private readonly string _key = default!;

    [RedisIdField] [Indexed] public string Id { get; set; }

   [Searchable]
   public string Key => !string.IsNullOrEmpty(_key)
    ? _key
    : Convert.ToBase64String(Encoding.UTF8.GetBytes($"{SelectionId}{Brand:D}{Segment:D}"));

    [Indexed] public int MarketId { get; set; }

    [Indexed] public long SelectionId { get; set; }

    public SegmentType Segment { get; set; }

    public BrandType Brand { get; set; }

    public int SingleTotalBets { get; set; }

    public double SingleTotalStake { get; set; }

    public double SingleTotalWon { get; set; }

    public double MultipleTotalStake { get; set; }

    public double MultipleTotalWon { get; set; }

    public double MultipleRealStake { get; set; }

    public double Slur0 { get; set; }

    public double Slur1 { get; set; }

    public double Slur2 { get; set; }

    public double Slur3 { get; set; }

    public double Slur4 { get; set; }

    public double Slur5 { get; set; }

    public long LastModifiedTimestamp { get; set; }
}

as you can see we used : [Searchable] Key field.

When I try to read from a multithread context the key, I get error like:

"An item with the same key has already been added. Key: xxxxxxxxx"

The stacktrace is:

System.ArgumentException
  HResult=0x80070057

  This exception was originally thrown at this call stack:
    [External Code]
    Phoenix.Risk.RunningOn.Application.Repositories.AggregationRepository.GetByKeyAsync(Phoenix.Risk.RunningOn.Domain.Entities.Aggregation, System.Threading.CancellationToken) in AggregationRepository.cs

I try to get the Document by the field "Key" and I get Error on method "InsertIntoData"
