Failed to read hupu hot threads: ${message}

Error message

Failed to read hupu hot threads: ${message}

What it means

getHupuHot navigates to bbs.hupu.com and runs buildHotScript(limit) inside the page to extract hot thread rows. If that page.evaluate throws (page unreachable, script error, markup mismatch causing a runtime exception), the error is wrapped as CommandExecutionError with the hint that the site may be unreachable or its markup changed.

Solutions

1. Retry the command — transient network or 5xx issues often resolve
2. Open https://bbs.hupu.com/ in a browser to confirm reachability and that the hot list renders
3. Inspect the inner error message (wrapped in this error) to see what the in-page script choked on
4. If markup changed, update buildHotScript selectors in clis/hupu/hot.js

Example fix

// before
const rows = await getHupuHot(page, 50);
// after
let rows;
try { rows = await getHupuHot(page, 50); }
catch (e) {
  console.error(e.message); // includes inner cause + hint
  rows = [];
}

const reachable = await fetch('https://bbs.hupu.com/', { method: 'HEAD' }).then(r => r.ok).catch(() => false);
if (!reachable) throw new Error('bbs.hupu.com unreachable — check network');

function isHotRows(v) {
  return Array.isArray(v) && v.length > 0 && v.every(r => r && typeof r === 'object');
}

try {
  rows = await getHupuHot(page, limit);
} catch (e) {
  if (/Failed to read hupu hot threads/.test(e.message)) {
    await sleep(3000); rows = await getHupuHot(page, limit); // one retry
  } else throw e;
}

When it happens

Trigger: page.goto to bbs.hupu.com succeeds but the injected buildHotScript evaluate throws — timeout, navigation interrupted, selectors/DOM assumptions in the script breaking, or the page serving an error/anti-bot page with no expected structure.

Common situations: No network access or DNS failure to bbs.hupu.com; Hupu redesigned the hot-list markup; anti-bot interstitial (captcha) replacing the homepage; transient 5xx from Hupu; slow load exceeding settle/wait budgets.
