.NET runtime version:net6.0

Operating system version:Windows 10 professional edition

Description of the problem including expected versus actual behavior:
Error is happend,and how to fix it.

Steps to reproduce:

public class buy
{
    [JsonPropertyName("Id")]
    /// <summary>
    /// 供求信息编号
    /// </summary>
    public int BuyId { set; get; }
    /// <summary>
    /// 用户编号
    /// </summary>
    /// 
    [JsonPropertyName("Userid")]
    public int Userid { set; get; }
    /// <summary>
    /// 标题
    /// </summary>
    /// 
    [JsonPropertyName("Title")]
    public string Title { set; get; }

    [JsonPropertyName("Ischengxin")]
    public int Ischengxin { set; get; }
}

var settings = new ElasticsearchClientSettings(new Uri("https://localhost:9200"))
.CertificateFingerprint("9d71addba27bb5efa9e8c45f529f3c9980314106acf62d46672c212c8053e2ee")//8.12 local
.Authentication(new BasicAuthentication("elastic", "xmdC3QQJmkZT5u=AdeOt"))//8.12 local
.DefaultMappingFor(i => i
.IndexName("buyindex")
.IdProperty(s => s.BuyId))
.EnableDebugMode();
var client = new ElasticsearchClient(settings);

        TermQuery aaa = new TermQuery("Ischengxin");
        aaa.Value = 1;
        Query qq = Query.Term(aaa);
        var bkt = new Buckets<Query>(new Dictionary<string, Query>
        {
            { "chengxin_filter",qq }
        }
        );

        var qr1 = client.Search<buy>(s => s
                       .Query(q => q
                       .MatchAll()
                       )
                       .Aggregations(a => a
    
                                       .Filters("f", c => c
                                                    .Filters(bkt)
                                                    .Aggregations(t => t
                                                            .Terms("Userid", ss => ss.Field(f => f.Userid).Aggregations(cc => cc.Max("maxBuyid", avg => avg.Field(p => p.BuyId))))

                                                   )

                                           )
                                   )
                       .Size(3)
                       .From(0)
                       );

Expected behavior

"f": {
"filters": {

"chengxin_filter": {
"term": {
"Ischengxin": {
"value": 1
}
}
}
}
},
"aggregations": {
"Userid": {
"terms": {
"field": "Userid"
},
"aggregations": {
"maxBuyid": {
"max": {
"field": "Id"
}
}
}
}
}
}
},
"query": {
"match_all": {}
}
}
