cloud cannot be nil

Error message

cloud cannot be nil

What it means

Defensive nil-check sentinel in PerformAssignments: the cloud interface argument is nil, so no cloud-specific defaults (network CIDRs, etcd, etc.) can be applied. Indicates a programming error in the caller — all listed callers (create/update/replace cluster flows) must pass an initialized cloud implementation.

Solutions

1. Ensure BuildCloud/cloud discovery succeeded before calling PerformAssignments
2. Check the --cloud/provider flag produced a valid cloud instance
3. Report as a bug if a valid cloud was expected
