Solutions

1. Confirm the seed page's static HTML contains links.
2. Verify sitemap.xml for xmlScrape.
3. Point the seed at a hub/listing page, not a leaf.
4. Provide selectedLinks explicitly.
5. Fall back to scraping the seed URL directly.

Example fix

// before
if (!pages || pages.length === 0) throw new Error('No relative links found')
// after
if (!pages || pages.length === 0) {
  options.logger.warn(`[${orgId}]: No relative links at ${url}; scraping seed only`)
  const seedDoc = await puppeteerLoader(url)
  if (seedDoc) docs.push(...seedDoc)
}

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) {
  const seedDoc = await puppeteerLoader(url)
  if (seedDoc) docs.push(...seedDoc)
}

When it happens

Trigger: webCrawl found no same-domain anchors; sitemap.xml empty/missing; selectedLinks empty after filtering; target is a JS SPA with no static links.

Common situations: SPA sites; disabled/missing sitemap; crawler blocked; selectedLinks input not wired.
