Fatal error - headers already sent, undefined index - woocommerce

[jeremyhalin]

Hi,
I have a fatal error no matter what endpoint I use.

Here is my php code where I make the request:

require __DIR__ . '/vendor/autoload.php';

use Automattic\WooCommerce\Client;

$woocommerce = new Client(
    'http://newsite.evp.fr', 
    'ck_***************', 
    'cs_***************',
    [
        'wp_api' => true,
        'version' => 'wc/v1',
    ]
);

$product = $woocommerce->get("products/1698");

And here are my server logs:

I'm totally lost here, don't know what to do to solve these errors...
Does any one had this issue before ?

Thanks.

Not an issue with this REST API lib, since don't have any woocommerce/includes/api/class-wc-rest-products-controller.php file inside this lib.
