Unable to find s-data in page

Error message

Unable to find s-data in page

What it means

The Baidu top route parses the hot-search board by finding an HTML comment inside #sanRoot whose data matches /s-data:(.*)/. If no such comment exists it throws 'Unable to find s-data in page', signalling that Baidu changed how it embeds the JSON payload (the comment-based SSR data injection).

Solutions

1. Fetch https://top.baidu.com/board?tab=realtime in a browser, view source, and locate where the JSON now lives.
2. Update the extraction at lib/routes/baidu/top.tsx:55 to read the new container (e.g. a script tag with JSON.parse).
3. If the data now comes from an XHR, call that API directly instead of scraping the HTML.

Example fix

// before
const sDataMatch = $('#sanRoot').contents().toArray().find(...)?.data.match(/s-data:(.*)/);
// after
const raw = $('#__NEXT_DATA__').text();
const { data } = JSON.parse(raw);

function pageHasSData($: ReturnType<typeof load>): boolean {
  const comment = $('#sanRoot').contents().toArray().find((e: any) => e.nodeType === 8);
  return !!comment && /s-data:/.test(comment.data ?? '');
}

const hasSDataComment = ($: ReturnType<typeof load>): boolean =>
  /s-data:/.test($('#sanRoot').contents().toArray().map((e: any) => e.data ?? '').join('\n'));

try {
  return await handler(ctx);
} catch (e) {
  if (e instanceof Error && /Unable to find s-data/.test(e.message)) {
    ctx.throw(502, 'Baidu top page markup changed - update extractor');
  }
  throw e;
}

When it happens

Trigger: The fetched top.baidu.com/board HTML contains no DOM comment under #sanRoot with 's-data:' prefix - Baidu moved the JSON to a script tag, an API call, or renamed the prefix.

Common situations: Baidu ships a frontend rewrite that embeds initial data via <script id="__NEXT_DATA__"> or a fetch call instead of the s-data comment; A/B exposure returning a different template; an anti-bot page returned instead of the real board.
