# `translation.option_unknown`

An option of translations in app.jadpo is not one it takes.

Area 10, [Configuration and time](../topics/configuration-and-time.md); not declinable; the next step is usually the agent's.

`translations:` in `application { }` takes `review:` and nothing else.

```jadpo
application {
    translations: {
        reviews: TranslationReview.required
    }
}
```

```text
error: `reviews` isn't an option of `translations`
 --> app.jadpo:3:9
  |
3 |         reviews: TranslationReview.required
  |         ^^^^^^^ unknown option
  reason: `translations:` in `application` takes `review:` and nothing else. Did you mean `review`?
  next: Use `review` instead of `reviews` (agent)
