Elasticsearch client query not working after update

I am using Elastic search for an ASP.NET MVC project. The Elasticsearch.Net client stopped working after a version update from 5.5.0 to 7.7.0. The type component has been removed from the query and there is a change in object serialization. I was trying to fix the query but I cannot be able to succeed.

I have attached the query code below.

Can anyone help me on this?

Thanks in advance.

What I have tried:

string postCode = "SW3";

var response = elasticClient.Search<AddressDom>(s => s.Index("new_address")
                     .Type("uk")              
              .From(0)
              .Take(100)
              .Query(qry => qry
                  .Bool(b => b
                  .Must(m => m
                      .QueryString(qs => qs
                          .DefaultField("Postcode")
                          .Query(postCode + "*").DefaultOperator(Operator.And)))))
                          .Sort(x => x.Field(cc => cc.Field("AreaTypeId").Descending())));
