Problem description

it can not work with this

Map<String, CompositeAggregationSource> map = new HashMap<>();
map.put("iids", CompositeAggregationSource.of(c -> c.terms(t -> t.field("iid").order(NamedValue.of("iid",SortOrder.Desc)))));

preview it to json

Hey, I also have the same issue, how do you solve it? any solution for it?

Same here. I have the same issue too. Looking forward to the fix.

In my case, it serialized to:

{
  "aggs": {
    "my_buckets": {
      "composite": {
        "sources": [
          { "date": { "date_histogram": { "field": "e", "calendar_interval": "1d",
          "order": [{"_key":"asc"}]
          } } } 
        ]
      }
    }
  }
}

Here is the error when sending the json request above to ElasticSearch:

{
  "error": {
    "root_cause": [
      {
        "type": "x_content_parse_exception",
        "reason": "[8:20] [date_histogram] order doesn't support values of type: START_ARRAY"
      }
    ],
    "type": "x_content_parse_exception",
    "reason": "[8:20] [composite] failed to parse field [sources]",
    "caused_by": {
      "type": "x_content_parse_exception",
      "reason": "[8:20] [date_histogram] order doesn't support values of type: START_ARRAY"
    }
  },
  "status": 400
}

what is meant by 9.10? is that the elastic version or the client version? when will it be released?
