Fatal error: Uncaught Elasticsearch\Common\Exceptions\BadRequest400Exception - php

Question

So I am using elasticsearch.
I have this code:
<?php
error_reporting(E_ALL);ini_set('display_errors', 1);
require 'vendor/autoload.php';
use Elasticsearch\ClientBuilder;
$hosts = [
'http://localhost:80', // SSL to localhost
];
$clientBuilder = ClientBuilder::create(); // Instantiate a new ClientBuilder
$clientBuilder->setHosts($hosts); // Set the hosts
$client = $clientBuilder->build();
$params = [
'index' => 'my_index',
'type' => 'my_type',
'id' => 'my_id',
'body' => ['testField' => 'abc']
];
$response = $client->index($params);
print_r($response);
I get this error:
Fatal error: Uncaught Elasticsearch\Common\Exceptions\BadRequest400Exception: 405 Method Not Allowed Method Not Allowed The requested method PUT is not allowed for the URL /my_index/my_type/my_id. in C:\Bitnami\wampstack-7.0.0RC7-\apache2\htdocs\vendor\elasticsearch\elasticsearch\src\Elasticsearch\Connections\Connection.php:615 Stack trace: #0 C:\Bitnami\wampstack-7.0.0RC7-\apache2\htdocs\vendor\elasticsearch\elasticsearch\src\Elasticsearch\Connections\Connection.php(279): Elasticsearch\Connections\Connection->process4xxError(Array, Array, Array) #1 C:\Bitnami\wampstack-7.0.0RC7-\apache2\htdocs\vendor\react\promise\src\FulfilledPromise.php(25): Elasticsearch\Connections\Connection->Elasticsearch\Connections{closure}(Array) #2 C:\Bitnami\wampstack-7.0.0RC7-\apache2\htdocs\vendor\guzzlehttp\ringphp\src\Future\CompletedFutureValue.php(55): React\Promise\FulfilledPromise->then(Object(Closure), NULL, NU in C:\Bitnami\wampstack-7.0.0RC7-\apache2\htdocs\vendor\elasticsearch\elasticsearch\src\Elasticsearch\Connections\Connection.php on line 615

I GOT IT!
I just had to change
$hosts = [
'http://localhost:80', // SSL to localhost
];
To
$hosts = [
'http://localhost:80' // SSL to localhost
];
(remove the comma)
