elasticsearch-php create index returns \BadRequest400Exception

I have a fresh installation of elasticsearch 5.0.0 and elasticsearch-php . I am trying to create an index.

I run the code from this index management documentation:

$client = ClientBuilder::create()->build();
$params = [
    'index' => 'my_index'
];

// Create the index
$response = $client->indices()->create($params);

and it works. I create an index successfully.

I try the next code snippet:

$client = ClientBuilder::create()->build();
$params = [
    'index' => 'my_index',
    'body' => [
        'settings' => [
            'number_of_shards' => 3,
            'number_of_replicas' => 2
        ],
        'mappings' => [
            'my_type' => [
                '_source' => [
                    'enabled' => true
                ],
                'properties' => [
                    'first_name' => [
                        'type' => 'string',
                        'analyzer' => 'standard'
                    ],
                    'age' => [
                        'type' => 'integer'
                    ]
                ]
            ]
        ]
    ]
];


// Create the index with mappings and settings now
$response = $client->indices()->create($params);

and I get:

Elasticsearch\Common\Exceptions\BadRequest400Exception with message 'No handler found for uri [/my_index] and method [POST]'

any ideas why?

This code used to work when I used elasticsearch 2.0

EDIT: I found this question so either it is a problem with elasticsearch-php or I need to update it I guess

I am using elasticquent which I have just realized requires elasticsearch-php version <2.2 so this is what is causing the problem
