…ents ParseObjects discarded errors in two cases: a strict-pass failure on a document of a known Argo kind (e.g. duplicate keys, which the non-strict unmarshal silently accepts) was dropped because the converted object was nil, and a document that is not valid YAML at all was only logged. The CLI lint then reported 'no linting errors found!' even though a linted file was broken, and the reporter could not tell which file was invalid when linting a directory. Parse errors are now returned in every ParseResult so that: - argo lint reports the file and the underlying error (and the object name/namespace when a kind was detected), and fails the lint - argo submit surfaces the error through SplitWorkflowYAMLFile instead of silently finding nothing to submit - documents that are not Kubernetes objects at all are reported by the linter and logged-and-skipped by the Split helpers (submit behaviour for mixed directories is unchanged)

📝 WalkthroughWalkthroughThe parser now returns YAML errors for invalid documents and strict conversion failures. Workflow splitters skip nil objects safely. The linter records parse errors with object indexes, and tests verify detailed messages for duplicate keys and malformed YAML. ChangesYAML error propagation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to Malformed documents for unknown Kubernetes kinds may still be silently omitted during linting, allowing a broken file to appear successful. The risk is bounded and mergeable with explicit owner awareness or follow-up to restrict fallback objects to supported Argo kinds.

Documentation and AI-use declarations are not included, but the description is otherwise complete and relevant. Full details: Linked Issues checkExplanation The changes satisfy issue Full details: Out of Scope Changes checkExplanation The changes remain related to YAML parse-error handling. Updates to ParseObjects and Split helpers support propagation of relevant errors while preserving behavior for non-Kubernetes documents. The added tests validate this behavior.

Detect known Argo kinds before creating the fallback object.
Line 56 accepts every non-empty kind, not only an Argo kind. If strict conversion fails for an unknown kind such as ConfigMap with duplicate YAML keys, objectForKind returns metav1.ObjectMeta. lintData then reaches its default branch and silently ignores the error.
Use an explicit Argo-kind check before constructing the typed fallback. Return {nil, err} for unknown kinds. Add a strict duplicate-key test for an unknown kind.

Fixes #9550
Motivation
argo lint ./on a directory where one file contains invalid YAML reports "no linting errors found!" and exits 0. Inworkflow/common/parse.go, a document of a known Argo kind whose strict parse fails (e.g. a duplicatetemplateskey, which the non-strict unmarshal silently accepts) was dropped because the converted object wasnil, and a document that is not valid YAML at all was only logged. Either way the error never reached the linter, so a user linting dozens of files could not tell which one was broken.Modifications
ParseObjectsnow returns every parse error in itsParseResultinstead of discarding them:{nil, err}instead of only logging it;Split*helpers propagate the strict error for Argo kinds (soargo submitsurfaces it instead of silently finding nothing) and log-and-skip documents that are not Kubernetes objects at all, keeping submit behaviour on mixed directories unchanged;lintDatareports nil-object parse errors with the file name through the existing formatters and marks the file as linted so the lint run fails.Verification
SplitWorkflowYAMLFilepropagates the error), an unparseable document is reported with the file name, a non-YAML document is still returned with its errorgo test ./workflow/common/ ./cmd/argo/lint/passes, also with-racego test ./workflow/... ./cmd/argo/... ./pkg/apiclient/... ./util/...: 48 packages ok;util/sqldbfails on clean main as well (requires Docker/testcontainers, unrelated to this change)Summary by CodeRabbit
