Unable to ensure load balancer due to service name

Hi, I'm trying to use ccm to setup load balancer, but service is failing to ensure load balancer with an error:

E1216 22:05:37.836237 1 controller.go:307] error processing service traefik/traefik (will retry): failed to ensure load balancer: rpc error: code = InvalidArgument desc = Validation failed:
- name: Field does not match the pattern /|[a-z][-a-z0-9]{1,61}[a-z0-9]/
I1216 22:05:37.836298 1 event.go:291] "Event occurred" object="traefik/traefik" kind="Service" apiVersion="v1" type="Warning" reason="SyncLoadBalancerFailed" message="Error syncing load balancer: failed to ensure load balancer: rpc error: code = InvalidArgument desc = Validation failed:\n - name: Field does not match the pattern /|[a-z][-a-z0-9]{1,61}[a-z0-9]/"

It looks like kubernetes concatenates namespace and service and Yandex Cloud API doesn't allow such names.

cluster version: v1.21.6

The issue names no file or test; start by tracing the load-balancer ensure path that handles the Kubernetes service name and the Yandex Cloud API validation error. Reproduce it with the traefik service in the traefik namespace, then verify that the resulting load balancer is accepted with a valid API name.
