form_field_unknown

HTTP 422 · code: "form_field_unknown" · type: https://docs.formfeed.dev/errors/form-field-unknown

/pdf/fill named a field the form does not have. The call was strict, which is the default, so nothing was filled and nothing was charged. field gives the name as you sent it. Fields are named by their full name, its parts joined by dots, as /pdf/info lists them.

Example

{
  "type": "https://docs.formfeed.dev/errors/form-field-unknown",
  "title": "Unknown form field",
  "status": 422,
  "detail": "The form has no field named \"customer.nme\"",
  "code": "form_field_unknown",
  "field": "customer.nme",
  "render_id": "rnd_0d290c45cbeb4554b946bbad1acee87e",
  "request_id": "req_4b7c1e9a2f3d4c5b8a6e7f9012"
}

Common causes

• A typo, or a name from another edition of the form.
• A short name where the form nests its fields: name for a field the form calls customer.name.

How to fix it

• List the form's fields with /pdf/info and take the names from form.fields.
• Send strict: false to leave names the form lacks out: the render's form.skipped lists them with the reason unknown.

Not with the same request: the form has no field of that name.
