Circular reference detected for service "knp_menu.matcher", path: "knp_menu.matcher -> sonata.admin.menu.matcher.voter.children -> knp_menu.matcher".
Intsall "knplabs/knp-menu-bundle": "2.1.3" even when I not use that bundle. So it seems it could be a knp-menu-bundle issue
Quick fix to carry on is to remove reference in the class in vendor/sonata-project/admin-bundle/ Resources/config/menu.xml
