elasticsearch create index meta error using php client

[sintret]

I am using elasticsearch for php client and this plugin. how to write "index" and "type" using php;
i have code like this :
$params['index'] = '_river';
$params['type'] = 'my_jdbc_river';
$params['body'] = [
'mapping' => [
'type' => 'jdbc',
'jdbc' => [
'url' => 'jdbc:mysql://localhost:3306/tourexplora',
"user" => "root",
"password" => "",
"sql" => "select *, id as _id from cities",
"index" => "teindex9",
"type" => "cities",
"bulk_size" => 500
]
]
];

    $ret = $this->client->indices()->create($params);

but errors shown like this:
exception 'Elasticsearch\Common\Exceptions\UnexpectedValueException' with
message 'type is not a valid parameter' in

The command is wrong. Do not use 'mapping' => [ ... ] There is no mapping. You must use HTTP PUT on the _meta endpoint. See the README.md

I can not find any example of river creation in official PHP client so I believe it is not supported.
