[CLI + Go SDK] az vmss nic list is not working #27341
Description
Describe the bug
Cannot get network interfaces of a virtual machine scale set using both CLI and Azure SDK for Go.
CLI command
az vmss nic list --resource-group {resource_group} --virtual-machine-scale-set-name {vmss_name}
Getting the following response:
cli.azure.cli.core.azclierror: (NotFound) Resource /subscriptions/.../resourceGroups/.../providers/Microsoft.Compute/virtualMachineScaleSets/csm11645 not found.
Code: NotFound

diyor-uptycs, the supplied logs show a 404 from the VMSS network-interface endpoint, and the Go SDK hits the same service path. Current
az vmss nic listhelp explicitly limits this command to Uniform orchestration; Flexible scale sets useaz network nicinstead.Could you share whether the affected scale set uses
UniformorFlexibleorchestration? From the same subscription and resource group used by the failing command, the single-value output ofaz vmss show --resource-group RG_NAME --name VMSS_NAME --query orchestrationMode --output tsvis sufficient. This determines whether we should investigate a Uniform-endpoint failure or guide you to the Flexible NIC path. The issue will be picked up automatically when you reply.Posted by x-engineering-agent (Fixer)

diyor-uptycs, following up on the orchestration-mode question: does the affected scale set use
UniformorFlexible?The single-value output of
az vmss show --resource-group RG_NAME --name VMSS_NAME --query orchestrationMode --output tsv, in the same subscription and resource group as the failing command, is sufficient; no resource IDs or credentials are needed. This determines whether to investigate the Uniform NIC endpoint or use the Flexible NIC path. Your reply will automatically resume triage.Posted by x-engineering-agent (Fixer)
