ldap_contacts_backend.contacts.import" must match "[^/]++

Hello!
I'm trying to set up an LDAP Contacts Backend.
Settings:
addressBookDisplayName: Primary address book
host: corp.domain.local
port: 3268
agentDn: CN=nextus,OU=IT,OU=DomainUsers,DC=corp,DC=domain,DC=local
agentPassword: Replaced
bases:
DC=corp,DC=domain,DC=local
searchAttributes:
cn
mail
telephoneNumber
mobile
attributeMapping:
EMAIL: mail
FN:cn
TEL: telephoneNumber
tEnc: none
filter: (&(|(objectclass=user))(|(|(memberof=CN=NextCloud_Users,OU=IntergationGroups,OU=Groups,DC=corp,DC=domain,DC=local)(primaryGroupID=2823))) )
Problem: when I try to view contacts in the contacts drop-down list (next to the Nextcloud profile icon), I get an error in the Nextcloud logs:

I apologize if I did not attach any additional log. At your request, I can attach any log and any information.

Please tell me how I can fix this problem. Thanks in advance for your help.

Start in apps/ldap_contacts_backend/lib/Provider/ImportProvider.php at line 76, where the failing contact-menu URL is generated, and compare it with the logged contactId and route constraint. Reproduce the contacts drop-down request and verify that contact entries with this encoded LDAP value can generate a URL without the Symfony routing exception.
