Hi @Zakharden. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Could a Kubernetes SIGs member please verify this PR for testing with /ok-to-test when available?

The change is focused on Helm chart rendering when a chart has no implicit values.yaml, while preserving errors for explicitly missing values files. I validated it locally with the targeted go test ./api/krusty ... coverage noted in the PR description.
@koba1t @sarab97

[Zakharden]

@koba1t @sarab97, give /ok-to-test plzzz

[Zakharden]

Quick nudge: this PR is still focused and ready for verification.
I rechecked local behavior around chart rendering when values file is missing + erroring when explicitly missing.
Could you please run path in bot by commenting so CI can proceed? / @koba1t @sarab97

[Zakharden]

Quick nudge: this PR is still focused and ready for verification. Could you please rerun your test flow so CI can proceed; thanks.

[Zakharden]

/ok-to-test is still required on this PR by your bot policy. No code changes from my side at this moment; once it is enabled I can push another no-op if needed for re-trigger.

[Zakharden]

No additional code changes were made after the last request. This PR is still blocked by bot policy as needs ok-to-test/approval workflow state.

I have not touched /lgtm as requested; please add approvals/verification (/ok-to-test) so regular CI can proceed.

[Zakharden]

Thanks for staying with this PR. I’ve not made additional code changes since last update; it remains blocked by /bot verification () and I have not touched . Please run approval/ok-to-test path so CI can proceed.

[Zakharden]

I’ve not made new code changes since the last update. This PR is still waiting on maintainer bot flow (needs-ok-to-test / approval path remains required), and I have not touched /lgtm. Please run the approval flow so CI can proceed.
