When i call a function get() from Elasticsearch\Namespaces\IndicesNamespace with multiple comma-separated list of features then it gives me error.
Uncaught Elasticsearch\Common\Exceptions\BadRequest400Exception: {"error":"Incorrect HTTP method for uri [/index1/_settings,_mappings] and method [GET], allowed: [POST]","status":405}
$params = [
'index' => 'index1',
'feature' => '_settings,_mappings',
];
$response = $client->indices()->get($params);
$response gives error as i said above.
