I stumbled onto this [discussion](https://discuss.elastic.co/t/elasticsearch-java-api-client-about-source-filtering-function/321173) while I was writing aggregation with limiting response to limited number of fields.

```auto
SearchRequest searchRequest = new SearchRequest.Builder()
    .index("idx_name")
    .query(query)
    .source(SourceConfig.of(s -> s.filter(f -> f.includes(List.of(// 10 fields // )))))
    .build(); 

```

My query :

```auto
"aggregations": {
    "someField": {
      "aggregations": {
        "documents": {
          "top_hits": {
            "size": 20,
            "_source": {
              "includes": [
                "field1",
                "field2",
                "field3",
                ..
                "fieldN"
              ]
            }
          }
        }
      },
      "terms": {
        "field": "someField",
        "size": 100
      }
    }
  }

```

if i add more than 3 fields, the client is not able to parse the response.

i tried my query with java api client setup using this tutorial : [Basic authentication | Elasticsearch Java API Client [8.12] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/8.12/_basic_authentication.html)

i get following error when i client tries to parse the response :

Method threw 'java.lang.NoSuchMethodError' exception. Cannot evaluate co.elastic.clients.elasticsearch.core.SearchResponse.toString()

Any guidance would be appreciated. thanks

Welcome!

What is the dependency tree?

```
mvn dependency:tree

```

Hi David,

I did a bit of reading and looks like the problem is with my index documents have both long and string mappings i.e. if I search with all String fields then no issues but on mixing them causes problem (mini problem).

and I was using jackson 2.10.x (big problem), upgrading to jackson 2.17.0 resolved it.

other configs java 8, es 8.12.x

thanks

This is well documented here:
