form_signed

HTTP 422 · code: "form_signed" · type: https://docs.formfeed.dev/errors/form-signed

The PDF given to /pdf/fill is signed: a signature field holds a signature, or the form says signatures exist. Filling it would change the signed file and invalidate its signatures, so nothing was filled and nothing was charged. /pdf/info says "signed": true for such a file.

Example​

{
  "type": "https://docs.formfeed.dev/errors/form-signed",
  "title": "Signed form",
  "status": 422,
  "detail": "antrag.pdf is signed, and filling it would invalidate its signatures",
  "code": "form_signed",
  "render_id": "rnd_0d290c45cbeb4554b946bbad1acee87e",
  "request_id": "req_4b7c1e9a2f3d4c5b8a6e7f9012"
}

Common causes​

  • A form signed by its author, or one filled and signed before it was sent on.

How to fix it​

  • Fill the form before it is signed, and sign the filled file.
  • Ask for an unsigned copy of the form.
