[BUG] Parsing histogram interval failed

[Degreeno]

What is the bug?

Creating a search with a histogram and interval will fail parsing with the error:
OpenSearch.Net.Utf8Json.JsonParsingException: expected:'Number Token', actual:'.', at offset:432

How can one reproduce the bug?

Just define an aggregation with an histogram and an interval.

var searchResponse = await _openSearchClient.SearchAsync<MetricInstance>(c => c
      .Index(GetIndexByDateTimeAndTenantUuidWithWildcards(IndexPattern, "*", tenantUuid))
      .Size(0)
      .Query(query => query
          .Bool(b => b
              .Must(must => must
                      .Terms(p =>
                          p.Field(field => field.DefinitionUuid)
                              .Terms(definition.Uuid)
                      )
              )
          )
      )
      .Aggregations(agg => agg
          .Histogram("aggregation_ranges", r => r
              .Field(f => f.Timestamp)
              .Interval(5000)
          )
      )
  );

What is the expected behavior?

It should not result in a parsing error.
