upgrading pipeline of profile

Error message

upgrading pipeline of profile %d: %w

What it means

For each profile index i, profiles() upgrades old.Profiles[i].Pipeline to the new struct and wraps any failure with 'upgrading pipeline of profile %d: %w'. The index is 1-based in the message to match human profile numbering in skaffold.yaml. The wrapped cause is the error returned by the versioned pipeline Upgrade() for that specific profile.

Solutions

1. Open the profile named by the index in skaffold.yaml and compare it against the target-version schema
2. Remove or migrate the unsupported field inside that profile's pipeline, then retry
3. Run `skaffold fix --profile <name>` if available to upgrade profile contents

Example fix

// before
profiles:
  - name: prod
    build:
      acr: {...}
// after
profiles:
  - name: prod
    build:
      artifacts: [...]

for i, p := range cfg.Profiles { if p.Build == nil || p.Deploy == nil { return fmt.Errorf("profile %d incomplete", i+1) } }

if err := util.UpgradePipelines(old, new, upgradeFn); err != nil {
	if m := regexp.MustCompile(`profile (\d+)`).FindStringSubmatch(err.Error()); m != nil {
		idx, _ := strconv.Atoi(m[1])
		// inspect cfg.Profiles[idx-1]
	}
}

When it happens

Trigger: Calling UpgradePipelines on a config where profile number N (message shows i+1) contains pipeline content the versioned Upgrade() rejects — removed fields, unsupported deployers, or malformed blocks only present in that profile.

Common situations: Profiles that carry legacy build/deploy config no longer supported in the target version; a profile overriding fields the main pipeline doesn't have, hitting an upgrade path only that profile exercises.
