Read Hupu mentions failed: invalid browser response

Error message

Read Hupu mentions failed: invalid browser response

What it means

The hupu mentions command evaluates an in-page script that fetches the mentions endpoint on my.hupu.com and returns a result object. If the evaluate yields null or a non-object (the script never produced a structured result), the library throws this CommandExecutionError because it cannot even classify success vs auth failure.

Solutions

  1. Log in to Hupu first (the sibling AuthRequiredError path only triggers for status 401/403 — a broken page yields this error instead), then retry
  2. Open my.hupu.com/mentions in a browser to confirm the endpoint responds
  3. Retry — transient navigation or network interruptions can yield a null evaluate result
  4. Inspect the injected script in clis/hupu/mentions.js and harden it to always return {status, ok, error} even on internal failure

Example fix

// before
if (!result || typeof result !== 'object') {
  throw new CommandExecutionError('Read Hupu mentions failed: invalid browser response');
}
// after (caller-side handling)
try { const m = await hupuMentions(page); }
catch (e) {
  if (/invalid browser response/.test(e.message)) await reloadAndLogin(page);
  else throw e;
}
Defensive patterns

Strategy: try-catch

Validate before calling

await page.goto('https://my.hupu.com/');
if (!page.url().includes('my.hupu.com')) await hupuLogin(page); // redirected to login

Type guard

function isValidMentionsResult(r) {
  return !!r && typeof r === 'object' && typeof r.status === 'number' && typeof r.ok === 'boolean';
}

Try / catch

try {
  const mentions = await hupuMentions(page);
} catch (e) {
  if (/invalid browser response/.test(e.message)) {
    await ensureHupuLogin(page);        // likely auth/captcha page
    mentions = await hupuMentions(page);
  } else throw e;
}

Prevention

When it happens

Trigger: page.evaluate in the mentions flow returns undefined/null — the injected async IIFE threw in a way that serialized to nothing, the page navigated away mid-evaluate, or the response could not be parsed into the expected {status, ok, data/error} shape.

Common situations: my.hupu.com serving an anti-bot/captcha page so the fetch wrapper is absent; navigation interrupted by a redirect to the login page; Hupu changing the mentions response shape so the script errors before returning; browser context closed.
