Error message

Unexpected evaluate response

What it means

After navigating to the note page and running NOTE_EXTRACT_JS via page.evaluate, the command expects an object result. If the evaluated script returns null, undefined, or a non-object, EmptyResultError('xiaohongshu/note', 'Unexpected evaluate response') is thrown — meaning the extraction script did not produce usable data rather than the note being missing.

Solutions

1. Retry — a not-yet-hydrated page is the most common cause.
2. Verify the URL renders a real note page in the logged-in browser.
3. Check for security-block/login pages manually; if present the session needs attention.
4. Regenerate a fresh URL with a valid xsec_token.

Example fix

// before
const data = await page.evaluate(NOTE_EXTRACT_JS); // too early
// after
await page.wait({ time: 4 });
const data = await page.evaluate(NOTE_EXTRACT_JS);
if (!data || typeof data !== 'object') throw new EmptyResultError('xiaohongshu/note', 'Unexpected evaluate response');

// Nothing to pre-validate client-side; ensure the URL is a valid signed note URL first
if (!/[?&]xsec_token=/.test(raw)) console.warn('URL lacks xsec_token; extraction may fail');

function isExtractPayload(v) {
  return !!v && typeof v === 'object' && !Array.isArray(v);
}

try {
  await note(url);
} catch (err) {
  if (err instanceof EmptyResultError && err.message.includes('Unexpected evaluate response')) {
    await sleep(3000);
    return note(url); // page likely hadn't hydrated
  } else throw err;
}

When it happens

Trigger: page.evaluate(NOTE_EXTRACT_JS) returns a non-object — the extraction script bailed early because the page structure was unexpected, the page did not finish rendering, or evaluate returned a wrapped/unserializable value.

Common situations: Slow network so the SPA hadn't hydrated despite the 2-5s random wait; XHS A/B page variants where selectors don't match; risk-control serving a blank shell page; xsec_token expired producing an odd page state.
