Why is the extracted content empty even though HTML was fetched?

Fetching HTML can still result in empty extraction if the main content has not loaded, the page redirected, or the content could not be extracted or validated. Work through these checks in order.

1. Switch to POST /v1/dom/dump in the playground. Check whether the HTML contains the main content and whether the final URL is correct.
2. If the content is present, check the extraction response for errors. For more detail, enable trace through the API to inspect processing steps, or use dom_id to extract again from the same page snapshot.
3. Keep the target URL, request_id, and error details. If the issue remains unresolved, share this diagnostic information with support after removing credentials and sensitive page content.
