ElasticSearch sort not working with es php library 8.2

Elastic Stack Elasticsearch
1

Hi All,

Trying to add sort option in query while retriving the data from Elasticsearch.
Have been getting the below error

PHP Fatal error: Uncaught Elastic\Elasticsearch\Exception\ClientResponseException: 400 Bad Request: {"error":{"root_cause":[{"type":"parsing_exception","reason":"request does not support [sort]","line":1,"col":186}],"type":"parsing_exception","reason":"request does not support [sort]","line":1,"col":186},"status":400} .

But the sort option works well in kibana dev tools. Is there any issue with the library?

Below is the query which i am trying

{
    "index": "indexname",
    "search_type": "dfs_query_then_fetch",
    "track_total_hits": true,
    "body": {
        "query": {
            "bool": {
                "must": [
                    {
                        "range": {
                            "amount": [
                                {
                                    "lte": 1500000
                                }
                            ]
                        }
                    }
                ],
                "should": [],
                "must_not": [],
                "filter": []
            }
        },
        "from": 0,
        "size": 100,
        "sort": {
            "name": {
                "order": "asc"
            }
        }
    }
}
