Empty content: ${articleUrl}

Error message

Empty content: ${articleUrl}

What it means

For each AI Base news item the route fetches the article HTML and reads the `.post-content` selector. If that selector yields no HTML (empty string), it throws a generic `Error('Empty content: <url>')`. Because this runs inside cache.tryGet, the failure (and any partial state) is not cached, but the whole feed fails.

Solutions

1. Open the failing articleUrl in a browser to confirm the markup.
2. If the selector changed, update '.post-content' to the new class as a maintainer.
3. Retry later for transient blocks; consider degrading to a title-only item instead of throwing.

Example fix

// before
const description = $('.post-content').html();
if (!description) throw new Error(`Empty content: ${articleUrl}`);
// after — tolerate missing body, keep the item
const description = $('.post-content').html() || $('.article-content').html() || 'Content unavailable';

function articleHasContent($ /*cheerio root*/) {
  return ($.html('.post-content') ?? '').trim().length > 0;
}

function hasPostContent(html): boolean {
  return typeof html === 'string' && html.trim().length > 0;
}

try {
  return await enrichAibaseArticle(articleUrl);
} catch (e) {
  if (e instanceof Error && /Empty content/.test(e.message)) {
    // fall back to a title-only item instead of failing the whole daily feed
    return { title: item.title, link: articleUrl, description: 'Content unavailable', pubDate: parseDate(item.addtime), author: 'AI Base' };
  }
  throw e;
}

When it happens

Trigger: The article page changed markup so `.post-content` no longer matches; the article is paywalled/removed; an anti-bot interstitial was returned instead of the article.

Common situations: Site redesign renamed the content class; CDN/WAF challenge on the per-article fetch; article deleted but still listed in the daily index.
