# `route.status_invalid`

Route status is not a `SuccessStatus`.

Area 7, [HTTP](../topics/http.md); not declinable; the next step is usually the agent's.

A success status is a `SuccessStatus`; failure statuses come from failure kinds:

```jadpo
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
        status: 201
        run: add_memo(input)
    }
}
```

```text
error: `201` isn't a success status
 --> main.jadpo:27:17
   |
27 |         status: 201
   |                 ^^^ not a `SuccessStatus`
  reason: `status:` takes `SuccessStatus.ok`, `.created`, `.accepted` or `.no_content`; failure statuses come from the kinds of the failures the route can produce, never from the route.
  next: Write `SuccessStatus.created` (agent)
