render_failed

The render engine could not produce the PDF — crashing HTML, a browser timeout, or a broken external resource.

How to fix it

Not necessarily your fault. Retry with backoff and the same idempotency_key; if it keeps failing, check the document for invalid markup or unreachable resources.
