unknown_field

HTTP 422

An unrecognized top-level field. Read valid_options + suggestion, or register it as a custom field (POST /v1/fields) and send it under custom_fields.

Every Relm error is RFC-9457 problem+json: type is this URI, plus title, status, detail, code, and — where a closed set exists — valid_options and a suggestion. See the error reference.
