No relative links found

Error message

No relative links found

What it means

Thrown by the Playwright loader when a relative-links crawl (webCrawl or xmlScrape) or provided selectedLinks yields zero pages. The crawl helpers returned an empty array, meaning no usable links were discovered from the seed URL.

Solutions

1. Verify the seed URL actually contains anchor tags in its served HTML (view-source).
2. For xmlScrape, confirm /sitemap.xml exists and lists URLs.
3. For webCrawl, ensure the seed page is the one that lists child links (not a leaf).
4. Provide selectedLinks explicitly if auto-discovery finds nothing.
5. Raise the limit / check that the site is reachable and not blocking the request.

Example fix

// before
const pages = relativeLinksMethod === 'webCrawl' ? await webCrawl(url, limit) : await xmlScrape(url, limit)
if (!pages || pages.length === 0) throw new Error('No relative links found')
// after - fall back to scraping the seed itself
if (!pages || pages.length === 0) {
  options.logger.warn(`[${orgId}]: No relative links found at ${url}; scraping seed only`)
  const seedDoc = await playwrightLoader(url)
  if (seedDoc) docs.push(...seedDoc)
}

// Probe whether the seed has crawlable links before committing
async function seedHasLinks(url) {
  const html = await (await fetch(url)).text()
  return /<a\s+[^>]*href=/i.test(html)
}

let pages = relativeLinksMethod === 'webCrawl' ? await webCrawl(url, limit) : await xmlScrape(url, limit)
if (!pages || pages.length === 0) {
  // fall back to scraping the seed itself rather than aborting
  const seedDoc = await playwrightLoader(url)
  if (seedDoc) docs.push(...seedDoc)
}

When it happens

Trigger: webCrawl found no same-domain links (JS-rendered SPA with no anchor tags in the static HTML); xmlScrape fetched sitemap.xml but it was empty, missing, or returned an error page; selectedLinks array was empty after filtering.

Common situations: Target site is a JS SPA whose links only render at runtime (Playwright scrape may still work but the link harvest runs on static HTML); robots.txt or sitemap.xml disabled; site blocks the crawler; selectedLinks input not wired up.
