Failed to find article content.

Error message

Failed to find article content.

What it means

Thrown when the Cheerio selector `.article-content` returns zero elements on the OpenAI help page for ChatGPT Atlas release notes. The handler fetches `https://help.openai.com/en/articles/12591856-chatgpt-atlas-release-notes`, loads it with Cheerio, and expects an element with class `article-content` to exist. Its absence means the page structure changed or the page did not load correctly.

Solutions

Open `https://help.openai.com/en/articles/12591856-chatgpt-atlas-release-notes` and inspect the page source for the current content container class.
Update the selector on line 33 of `lib/routes/openai/chatgpt-atlas.ts` to match the new class name.
If the page is now client-rendered, switch to Puppeteer or find the underlying API endpoint.
Verify the article URL is still valid and not redirected.

Example fix

// before
const articleContent = $('.article-content');
if (articleContent.length === 0) {
    throw new Error('Failed to find article content.');
}

// after — try multiple known selectors
const articleContent = $('.article-content').length ? $('.article-content') : $('article');
if (articleContent.length === 0) {
    throw new Error('Failed to find article content.');
}

Defensive patterns

Strategy: try-catch

Validate before calling

// Pre-check: verify the article page contains expected content markers
const response = await ofetch(articleUrl);
if (!response.includes('article-content') && !response.includes('<article')) {
    throw new Error('OpenAI help page structure may have changed');
}

Try / catch

try {
    const response = await ofetch(articleUrl);
    const $ = load(response);
    const articleContent = $('.article-content');
    if (articleContent.length === 0) {
        throw new Error('Failed to find article content.');
    }
} catch (e) {
    logger.error('OpenAI Atlas help page could not be parsed: HTML structure may have changed');
    throw e;
}

Prevention

Use multiple fallback selectors instead of relying on a single class name.
Monitor the OpenAI help center for template changes.
Cache successful parses to reduce the impact of transient page structure issues.

When it happens

Trigger: The OpenAI help center changed its HTML template (removing or renaming the `article-content` class). The page returned a JS-rendered SPA shell with no server-side content. The article URL was changed or the article was taken down. A CDN error page was served instead.

Common situations: OpenAI redesigned their help center. The article ID `12591856` was changed. The help center now requires JavaScript rendering (client-side hydration) that Cheerio cannot execute.
