Hello.
Tell me the probable cause of these records?

You are calling elasticsearch with a body without specifying the Content-Type.

I specify so, but still there is a WARN

    <?php
    curl_setopt($ci, CURLOPT_URL, 'http://127.0.0.1:9200/index/type/');
    curl_setopt($ci, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ci, CURLOPT_FORBID_REUSE, 0);
    curl_setopt($ci, CURLOPT_HTTPHEADER, ['Content-Type: application/json; charset=UTF-8']);
    curl_setopt($ci, CURLOPT_POST, true);
    curl_setopt($ci, CURLOPT_POSTFIELDS, json_encode($data_query, JSON_UNESCAPED_UNICODE));
    ...
    ?>

I don't know. What happens if you do that with curl instead of PHP?

The error went away. This was due to running scripts.
Thank you. The problem is solved.
