Circular Reference in JSON Serialization of Nest.DSL.Search.SearchSourceDescriptor<T>

[nariman-haghighi]

Here's the query:

  public IEnumerable<string> GetDocumentIds(Guid userId)
  {
      var queryResults = new ElasticClient(SearchSettings).Search<Media>(x => x
              .Index("Media")
              .Source(s => s.Include(m => m.Id))
              .Size(5000)
              .Query(p => p.Term(f => f.UserId, userId.ToString())));

      return queryResults.Documents.Select(m => m.Id);
  }

Exception: Newtonsoft.Json.JsonSerializationException: Self referencing loop detected for property 'self' with type 'Nest.DSL.Search.SearchSourceDescriptor`1[Data.Model.Media]'. Path '_source'.

The offending property seems to be in: NEST.ISearchRequest.Source

Thank you for catching this one @nariman-haghighi 👍

The .Source() code path only had integration tests and no unit tests. Unit tests are run as part of the continuous builds but integration tests are not.
