querying all selectors %q: %w

Error message

querying all selectors %q: %w

What it means

queryAll evaluated the injected js.QueryAll script in the element's context and the evaluation failed (element_handle.go:1272). The wrapped error is a CDP/evaluation error — context destroyed by navigation, target closed/crashed — identical in nature to the $() evaluation failure but on the multi-select path.

Solutions

1. Wait for load state after navigating actions before $$
2. Re-query the base element handle after navigation — the old handle's context is gone
3. try/catch with one retry for transient races
4. If crashes correlate with VU load, reduce parallelism or check chromium memory

Example fix

// before
await page.click('button.load-more');
const items = await page.$$('.item'); // may race the re-render
// after
await page.click('button.load-more');
await page.waitForLoadState('networkidle');
const items = await page.$$('.item');

await page.waitForLoadState('domcontentloaded');
if (!(await el.isVisible())) throw new Error('element context probably navigated away');

try { return await el.$$(sel); }
catch (e) {
  if (/querying all selectors/.test(e.message)) { await page.waitForLoadState(); return await el.$$(sel); }
  throw e;
}

When it happens

Trigger: Navigation, iframe removal, or page close between the $$ call and evaluation; browser crash under load; stale element handle from a previous document.

Common situations: Scraping all rows right as an SPA transitions routes; browser teardown racing pending $$ promises at k6 iteration end.
