Versions

CCM Version:
V1.23.0
Environment:

• Kubernetes version (use kubectl version): v1.23.4
• OS (e.g. from /etc/os-release): Oracle Linux Server 7.9
• Kernel (e.g. uname -a): 5.4.17-2136.309.5.el7uek.x86_64
• Others:

What happened?

Created a load balancer service successfully, and then a NLB was created automatically.
But access the service failed, then check the NLB, there was no member in backend.

What you expected to happen?

The load balancer service can be accessed successfully.

How to reproduce it (as minimally and precisely as possible)?

CCM was installed as doc

Start with the logged paths in oci/load_balancer.go, oci/load_balancer_spec.go, and node_controller.go, focusing on how an empty node ProviderID affects NLB backend creation and instance metadata lookup. Reproduce with the reported Kubernetes and CCM versions, then verify that created NLB services receive backend members and no longer emit the ProviderID errors.
