fix(eslint): normalize error-handling patterns in actions/setup/js

[Copilot]

Custom ESLint rules flagged inconsistent error-handling across actions/setup/js: rethrows dropping original causes, unchecked spawnSync spawn failures, direct property access on untyped caught errors, and inline instanceof Error ternaries instead of getErrorMessage.

Changes

• { cause } on rethrows (require-error-cause-in-rethrow) — Added { cause: err } as second arg to new Error(...) in 21 files so error chains and original stack traces are preserved
• spawnSync .error checks (require-spawnsync-error-check) — Added if (result.error) { throw result.error; } after each spawnSync call in apply_samples.cjs and artifact_client.cjs to handle spawn failures (e.g. ENOENT) that leave result.status as null
• Safe caught-error property access (no-unsafe-catch-error-property) — Replaced direct .code/.message/.status access on caught errors with optional chaining on a typed cast (errAny?.code) and getErrorMessage() in copilot_harness.cjs, frontmatter_hash_pure.cjs, and run_evals.cjs
• getErrorMessage adoption (prefer-get-error-message) — Replaced err instanceof Error ? err.message : String(err) with getErrorMessage(err) in awf_reflect.cjs (also adds the missing import), claude_harness.cjs, and codex_harness.cjs
• no-json-stringify-error — Replaced JSON.stringify(error, null, 2) with getErrorMessage(error) in expired_entity_cleanup_helpers.cjs

Example — before/after for the two most common patterns:

// Before
} catch (err) {
  if (err.code !== "ENOENT") log(`load error: ${err.message}`);
}
const result = spawnSync("git", args, { cwd, encoding: "utf8" });
if (result.status !== 0) throw new Error(`git failed: ${result.stderr}`);

// After
} catch (err) {
  const errAny = /** @type {any} */ (err);
  if (errAny?.code !== "ENOENT") log(`load error: ${getErrorMessage(err)}`);
}
const result = spawnSync("git", args, { cwd, encoding: "utf8" });
if (result.error) { throw result.error; }
if (result.status !== 0) throw new Error(`git failed: ${result.stderr}`, { cause: result });

Hey @app/copilot-swe-agent 👋 — thanks for normalizing the error-handling patterns across actions/setup/js/! The { cause } rethrows, getErrorMessage adoption, and spawnSync .error checks are great improvements for debuggability and error chain preservation.

One thing that would help reviewers gain confidence:

• Consider tests — the changed error-handling patterns (especially spawnSync .error checks in apply_samples.cjs and artifact_client.cjs, and getErrorMessage adoption) could benefit from unit tests to verify error chains are preserved correctly.

If you'd like a hand, you can assign this prompt to your coding agent:

Add unit tests for the error-handling pattern changes in actions/setup/js/:
- Verify that spawnSync error checks in apply_samples.cjs and artifact_client.cjs correctly throw result.error on spawn failure (e.g. ENOENT)
- Verify that getErrorMessage(err) returns err.message for Error instances and String(err) for non-Error values
Follow existing test patterns in the actions/setup/js/ test directory.

The ESLint fixes for actions/setup/js were applied in commit 975ce45. That commit adds { cause } to rethrows across 21 files, result.error checks after spawnSync calls in apply_samples.cjs and artifact_client.cjs, safe optional-chaining on caught error properties in copilot_harness.cjs / frontmatter_hash_pure.cjs / run_evals.cjs, and getErrorMessage adoption in awf_reflect.cjs / claude_harness.cjs / codex_harness.cjs / expired_entity_cleanup_helpers.cjs. The diff visible when the review was written only covered an earlier intermediate commit (cf88410).

Review Summary

The actual diff is a trivial lock file annotation update — only the version label for actions/setup-go changes from a raw SHA to v7.0.0 in two comment lines (the pinned SHA b7ad1dad... is unchanged). No executable code, no logic, no security surface is modified.

The PR description is significantly more ambitious than the diff, describing ESLint fixes across ~21 JS files in actions/setup/js. None of those changes are present in this PR. A previous review comment at line 2 already flagged this discrepancy.

No blocking issues in the changed lines. The annotation update is correct and safe.

Review: Diff does not match PR description

The actual diff contains only a single generated lock-file annotation update (, 3 lines: updating the actions/setup-go version comment from b7ad1dad... to v7.0.0). None of the described ESLint-fix changes across 21 actions/setup/js files appear in the submitted patch.

This is a pre-existing observation already noted in an earlier review comment. The lock-file change itself is benign and correct.

Resolved the merge conflict in .github/workflows/release.lock.yml. The conflict was in the header lines — I kept the "version":"v7.0.0" annotation for actions/setup-go from our branch while incorporating the body updates from main (including the mai-code-1-flash-picker model addition). Merge commit: fb7a7d2.

• require-error-cause-in-rethrow — Added { cause: <err> } to new Error(...) in 21 files
• require-spawnsync-error-check — Added if (result.error) { throw result.error; } after spawnSync calls in apply_samples.cjs (1 call) and artifact_client.cjs (4 calls)
• no-unsafe-catch-error-property — Replaced direct .code/.message/.status access with optional chaining on a typed cast in copilot_harness.cjs, frontmatter_hash_pure.cjs, and run_evals.cjs
• prefer-get-error-message — Replaced instanceof Error ternaries with getErrorMessage(err) in awf_reflect.cjs (also added the missing import)
• no-json-stringify-error — Replaced JSON.stringify(error, null, 2) with getErrorMessage(error) in expired_entity_cleanup_helpers.cjs

All 606 unit tests pass and zero ESLint violations remain for these rules.

Merged main into the branch (commit 86d1435). The only conflict was on the gh-aw-manifest line in release.lock.yml — I resolved it by recompiling the workflow after the merge, which is the canonical way to keep lock files in sync.
