No LinkedIn Learning course found for slug "${slug}"

Error message

No LinkedIn Learning course found for slug "${slug}"

What it means

The API responded correctly with a well-formed elements array, but it is empty — LinkedIn has no course matching the requested slug. This is thrown as an EmptyResultError to signal 'query valid, nothing found' rather than a malfunction.

Solutions

1. Verify the slug against the course's live URL (https://www.linkedin.com/learning/<slug>/) and fix typos.
2. Use the linkedin-learning search command with the course title to find the current slug.
3. Check whether the course was retired or is region/language-restricted for your account.

Example fix

// before
opencli linkedin-learning course 'agentic-ai-build-your-first-agentik-ai-system'  // typo
// after
opencli linkedin-learning course 'agentic-ai-build-your-first-agentic-ai-system'

// Validate the slug exists by opening its public URL first (optional):
const res = await fetch(`https://www.linkedin.com/learning/${slug}/`, { method: 'HEAD' });
if (res.status === 404) console.warn(`Slug "${slug}" may not exist`);

function isPlausibleSlug(v) {
  return typeof v === 'string' && /^[a-zA-Z0-9-_]{3,}$/.test(v);
}

try {
  return await runCommand('linkedin-learning', 'course', [slug]);
} catch (e) {
  if (e instanceof EmptyResultError || e.message.startsWith('No LinkedIn Learning course found')) {
    return runCommand('linkedin-learning', 'search', [slugToKeywords(slug)]); // fallback to search
  }
  throw e;
}

When it happens

Trigger: Calling linkedin-learning course with a syntactically valid slug (passes ^[a-zA-Z0-9-_]+$) that does not correspond to an existing/published LinkedIn Learning course, so elements[0] is undefined.

Common situations: Typo in the slug; course retired or region-restricted (unavailable in the account's locale); slug belongs to a learning path or video rather than a course; wrong localized slug.
