`file_not_found`

HTTP 422 · Do not retry unchanged — fix the request first

No uploaded file was found for that upload_id.

What happened

The upload_id is unknown, the upload was never actually performed, or it expired.

Uploads that are never referenced by an order are deleted after 14 days.

Request a slot with POST /v1/uploads, then PUT the file content to the returned upload_url, then reference the upload_id in the order.
When repeating an order, reuse the same upload_id values — the duplicate protection recognises them.

Repeating the request unchanged will fail again. Correct the request first — the response tells you which part is wrong.
