I have the user backend as LDAP.

Do you know what should I do ?

Start with apps/circles/lib/Model/ModelManager.php and apps/circles/lib/Model/Circle.php, following the generation of the contacts.contacts.directcircle route URL into FederatedUserService.php. Reproduce or trace the background-job path shown in the report and identify why that named route is unavailable; done means the recurring RouteNotFoundException no longer appears in the logs.
