I am using the Elasticsearch PHP package for execute queries. When I execute this basic search query, i get the `illegal_argument_exception` . The function `elastic()` returns the Client of Elasticsearch.

```
$query = $this->elastic()->search([
    'index' => ['my_index'],
    'type' => 'my_type',
    'from' => 0,
    'size' => 10,
    'body' => [
        'query' => [
            'match_all' => (object)[],
        ]
    ]
]);

```

Error:

```
{
    "type": "illegal_argument_exception",
    "reason": "field name is null or empty"
}
```
