Impact

Unable to ingest service.

The process involves using a specific code to locate and identify the vSphere Cluster Services virtual machines (vCLS VMs) within a VMware cluster. This code initiates a comprehensive scan of all the VMs present in the cluster by accessing vCenter. If one of those VMs is currently inaccessible, it returns a nilClass empty error, thus causing the failure. Any inaccessible VM triggers this error.

Address the issue of the inaccessible VMs by either restoring them from backup or removing them from the inventory. Once this is done, retrying the operation should be successful.
