Error message

字幕获取失败: ${err?.message || err}

What it means

A CommandExecutionError thrown when the in-page fetch of the subtitle CDN JSON file throws — the browser-side evaluate() rejected. The library wraps any page.evaluate failure and rethrows with the underlying message. This is about the network fetch of the subtitle file, not the earlier API call.

Solutions

1. Re-run the command to get a fresh subtitle_url — CDN tokens expire.
2. Check network connectivity / proxy settings affecting Chrome.
3. Increase browser/CLI timeouts if the page is being torn down mid-fetch.
4. If persistent, verify the URL manually in Chrome and check for HTTP error status.

// Pre-flight: confirm Chrome can reach the CDN host before the run:
await fetch('https://api.bilibili.com/x/web-interface/nav', { method: 'HEAD' }).catch(() => { throw new Error('network unavailable'); });

try {
  await run('bilibili subtitle', { url });
} catch (e) {
  if (/字幕获取失败/.test(e.message)) {
    await sleep(5000);
    return run('bilibili subtitle', { url }); // fresh token, fresh fetch
  }
  throw e;
}

When it happens

Trigger: page.evaluate(fetchJs) rejects: network failure reaching the CDN URL, CORS/blocked fetch inside the page context, page navigated/closed mid-evaluate, or the browser context was destroyed.

Common situations: Expired CDN signed URLs (subtitle_url tokens expire); offline/proxy network issues; browser tab closed by timeout; CDN returning errors that surface as fetch rejection (rare, usually fetch resolves with res.ok false).
