Error message

Could not find chart data on page

What it means

The imdb top command throws CommandExecutionError('Could not find chart data on page') when extractJsonLd(page, 'ItemList') returns null or the result lacks an array itemListElement. The Top 250 chart page loaded without a challenge, but the expected ItemList JSON-LD block holding the chart entries is missing or malformed.

Solutions

1. Retry the command — a slow render can leave JSON-LD missing after the fixed 2s wait.
2. Increase the wait time before extraction if the library allows configuration.
3. Check imdb.com/chart/top/ in a browser; if the structure changed, the library needs an update.

Example fix

// before
const top = await imdbTop({ limit: 10 }); // threw: chart data missing
// after
await sleep(1000); // give SPA more time, then retry once
const top = await retry(() => imdbTop({ limit: 10 }), { attempts: 2 });

try {
  return await imdbTop({ limit });
} catch (e) {
  if (/Could not find chart data/.test(e.message)) {
    await sleep(5000);
    return retryWithBackoff(() => imdbTop({ limit }), { attempts: 2 });
  }
  throw e;
}

When it happens

Trigger: After a successful, non-challenged load of https://www.imdb.com/chart/top/ and page.wait(2), extractJsonLd(page, 'ItemList') yields no object, or ld.itemListElement is not an Array.

Common situations: IMDb redesigning the chart page and dropping/moving the ItemList JSON-LD, a partial render where JSON-LD hasn't been injected after only a 2-second wait, or a regional variant of the page with different markup.
