Error message

joinup: ${entry.name} page is missing __NEXT_DATA__ (structure changed?)

What it means

Thrown by joinup.fetch() when the fetched joinup.ch browse page HTML has no <script id="__NEXT_DATA__"> tag matching the provider's regex. Like the join.com provider, joinup scrapes server-rendered Next.js data; a missing tag is treated as a scraper break (board redesign, error page, or bot challenge) and fails closed so the scan logs it instead of silently reporting zero jobs.

Solutions

1. Open the BROWSE_URL in a browser and confirm a __NEXT_DATA__ script tag is present.
2. If the page is a bot challenge, slow down scans or route through a residential context.
3. If joinup.ch redesigned, update the regex / data-access path in providers/joinup.mjs to match the new structure.

async function joinupHasNextData(fetchText, browseUrl) {
  const html = await fetchText(browseUrl, { redirect: 'error' });
  return /<script id="__NEXT_DATA__"[^>]*>[\s\S]*?<\/script>/.test(html);
}

try {
  jobs = await provider.fetch(entry, ctx);
} catch (err) {
  if (/missing __NEXT_DATA__/.test(err.message)) {
    console.error(`joinup ${entry.name}: board missing __NEXT_DATA__ — redesign or block`);
  }
  throw err;
}

When it happens

Trigger: joinup.ch redesigned its page and removed or renamed the __NEXT_DATA__ script; the request returned a non-board HTML (403/429/500, Cloudflare interstitial, maintenance page); the BROWSE_URL constant is stale and points at a retired route.

Common situations: joinup.ch shipped a frontend change; rate-limiting or geo-blocking returned a challenge page instead of the board; the site moved to a different rendering strategy (no SSR Next.js).
