VMSS %s has no network profile

Error message

VMSS %s has no network profile

What it means

Fires in toVMScaleSetResource when the VMSS's Properties, VirtualMachineProfile, or network profile chain is nil, so Azure resource discovery cannot extract vnets/subnets/ASGs/load balancers that the VMSS deletion blocks on.

Solutions

1. Inspect the VMSS in the Azure portal/CLI — it may be mid-provisioning or partially deleted
2. Retry discovery once the VMSS has a complete network profile
3. If the VMSS is orphaned/broken, delete it directly in Azure and re-run kops delete
