# NAB's CDR Banking API follows the DSB Consumer Data Standards (CDS) error model,
# NOT RFC 9457 problem+json. Errors are returned in a ResponseErrorListV2 envelope:
#   { "errors": [ { "code": "<urn>", "title": "...", "detail": "...", "meta": {...} } ] }
# Codes below are the standardized CDS error identifiers referenced by the spec's
# per-operation response descriptions (anchor slugs preserved verbatim from the spec).
format: cds-error-list

  field: errors
  item_fields: [code, title, detail, meta]
