route.item_duplicate

Route item is given twice.

Area 7, HTTP; not declinable; the next step is usually the agent's.

Each item is given once:

example
type Memo = Text {    max_length: 200}type MemoId = Uuid {}type AddMemo = Input {    text: Memo}type MemoView = Output {    text: Memo}action add_memo(input: AddMemo) -> MemoView {    return MemoView {        text: input.text    }}routes Memos {    prefix: /memos    POST / {        input: AddMemo        output: MemoView        run: add_memo(input)        run: add_memo(input)    }}
