Filter module Error: 0

-- HikaShop version -- : 6.0.0
-- Joomla version -- : 5.3.1
-- PHP version -- : 8.2.28
-- Browser(s) name and version -- : Firefox 140.0.2
-- Error-message(debug-mod must be tuned on) -- : Call to a member function get() on null

Morning,

after the update to 6.0.0 (com_hikashop_business_v6.0.0_2025-07-02_16-13-06) all pages with the filter module give the following error: Call to a member function get() on null.

For the error report see the attached image.

The error seems to originate from the first reported error line:

JROOT/administrator/components/com_hikashop/classes/filter.php:2853

$step = $config->get('non_price_filter_step', '0.01');
if(in_array($filter->filter_data, array('price', 'b.product_sort_price'))) {
$step = '0.01';
}

I did remove the above code and all seems to be working.
