error getting cloud instance group %q: %v

Error message

error getting cloud instance group %q: %v

What it means

Wraps buildCloudInstanceGroup failure while constructing a cloudinstances.CloudInstanceGroup for a DO droplet group — i.e. enumerating the group's droplet members failed (droplet lookups by ID). Prevents rolling-update logic from acting on incomplete instance data.

Solutions

1. Check the wrapped error for which droplet lookup failed
2. Verify droplets in the group still exist and are readable
3. Retry after DO API issues resolve
