PHP Fatal error: Uncaught PodioUnavailableError

API method that I'm using:

$attributes = array();
        $attributes['sort_by'] = 'created_on';
        $attributes['sort_desc'] = true;
        $attributes['filters'] = array("created_on" => array("from" => "2022-01-01","to" => "2022-09-30"));
        $attributes['limit'] = 500;
        $attributes['offset'] = 500;
        $attributes['remember'] = false;
        $AppData = PodioItem::filter( $app_id, $attributes, $options = array() );

I set the limit => 500 it is working fine sometimes but at the same time if I try to get another 500 items with 500 offsets I'm getting an error and at the very next moment without any change, I try again and it works. Looks likes something happing on server side.

The error that I'm getting:
