Invalid JSON returned

[ad-on-is]

I would like to list all products, therefore I used the filter[limit] like this

$woocommerce->get('products', array('filter[limit]' => 10000, 'fields' => 'id,title,sku,variations'));

Unfortunately I get PHP-error message saying

Fatal error: Uncaught exception 'Automattic\WooCommerce\HttpClient\HttpClientException' with message 'Invalid JSON returned' in /var/www/html/wcapi/src/WooCommerce/HttpClient/HttpClient.php:303 Stack trace: #0 /var/www/html/wcapi/src/WooCommerce/HttpClient/HttpClient.php(346): Automattic\WooCommerce\HttpClient\HttpClient->lookForErrors(NULL) #1 /var/www/html/wcapi/src/WooCommerce/HttpClient/HttpClient.php(382): Automattic\WooCommerce\HttpClient\HttpClient->processResponse() #2 /var/www/html/wcapi/src/WooCommerce/Client.php(82): Automattic\WooCommerce\HttpClient\HttpClient->request('products', 'GET', Array, Array) #3 /var/www/html/wcapi/wcapi.php(1189): Automattic\WooCommerce\Client->get('products', Array) #4 {main} thrown in /var/www/html/wcapi/src/WooCommerce/HttpClient/HttpClient.php on line 303

Is there a way to list all products?

Are you using some plugin for cache?

[ad-on-is]

No. W3TotalCache is deactivated on dev-environment.
Tried with and without php-opcache.

I have analysed it a bit more. It works when I set the limit to something like 2000 and lower.

[claudiosanches]

@ad-on-is seems like a timeout problem.

[ad-on-is]

$woocommerce = new Client(
    'http://project.local', 
    'ck_xxx', 
    'cs_xxx',
    array(
        'timeout' => 1000
    )
);

this is what my settings look like.

in php.ini I've set:
max_execution_time = 0 and max_input_time = -1

[claudiosanches]

Still don't seems an error on this wrapper.
The error that you are reporting may appear in when PHP throw any kind of warning. Since will mix HTML and JSON.
Have you checked it?

[ad-on-is]

Since will mix HTML and JSON.

I don't actually understand what you mean here. The returning JSON can contain HTML-Content in the product-description which is post_content itself.

[claudiosanches]

PHP warning (HTML) + JSON.
Have you enabled WordPress Debug mode?

[ad-on-is]

Debug mode is disabled.
I wanted to check $this->response->getBody() what it actually returns before it's sent to lookForErrors() in HttpClient.php on line 344, but I get an empty string there.

[claudiosanches]

@ad-on-is you can use:

use Automattic\WooCommerce\HttpClient\HttpClientException;

try {
    // Your request here!
} catch (HttpClientException $e) {
    \print_r($e);
    \print_r($e->getMessage() . PHP_EOL);
    \print_r('Code: ' . $e->getResponse()->getCode() . PHP_EOL);
    \print_r('Body: ' . $e->getResponse()->getBody() . PHP_EOL);
}

$e->getResponse()->getBody() will return the raw response.

This is what i get:

Well, updating from woocommerce 2.5.2 to 2.5.5 solved the issue

[claudiosanches]

For some reason is returning empty, probably because of an error... But really not an issue in this wrapper.

[apuestaya]

Hi, @ad-on-is, did you found solution for this issue?
Thank you!
