Fatal error: Uncaught ArgumentCountError: Too few arguments to function MGSAjaxlayernavigationModelLayerFilterItemBuilder::addItemData(), 3 passed in /opt/bitnami/apps/magento/htdocs/app/code/MGS/Ajaxlayernavigation/Model/Layer/Filter/Attribute.php on line 172 and exactly 5 expected in /opt/bitnami/apps/magento/htdocs/app/code/MGS/Ajaxlayernavigation/Model/Layer/Filter/ItemBuilder.php:8 Stack trace: #0 /opt/bitnami/apps/magento/htdocs/app/code/MGS/Ajaxlayernavigation/Model/Layer/Filter/Attribute.php(172): MGSAjaxlayernavigationModelLayerFilterItemBuilder->addItemData('Feuchtigkeit', '715', 0) #1 /opt/bitnami/apps/magento/htdocs/app/code/MGS/Ajaxlayernavigation/Model/Layer/Filter/DefaultFilter.php(117): MGSAjaxlayernavigationModelLayerFilterAttribute->_getItemsData() #2 /opt/bitnami/apps/magento/htdocs/app/code/MGS/Ajaxlayernavigation/Model/Layer/Filter/DefaultFilter.php(98): MGSAjaxlayernavigationModelLayerFilterDefaultFilter->_initItems() #3 /opt/bitnami/apps/magento/htdocs/app/code/MGS/Ajaxlayernavig in /opt/bitnami/apps/magento/htdocs/app/code/MGS/Ajaxlayernavigation/Model/Layer/Filter/ItemBuilder.php on line 8

I've already been able to fix the error, but I'm not sure if that's correct.
I made the following customization in the file \ app \ code \ MGS \ Ajaxlayernavigation \ Model \ Layer \ Filter \ Attributes.php 172:
168} else {
169 $ this -> _ itemBuilder-> addItemData (
170 $ this-> tagFilter-> filter ($ option ['label'])
171 $ option ['value'],
172 isset ($ optionsCount [$ option ['value']])? $ optionsCount [$ option ['value']]: 0,
173 zero,
174 null
175);
176}
