# `migration.decision_required`

Migration needs a decision.

Area 5, [Data](../topics/data.md); not declinable; the next step is usually the human's.

`stars` is new and required; `jadpo migrate new add_stars` wrote the migration and left the decision to fill in:





```jadpo
migration {
    Note.stars: {}
}
```

```text
error: Migration `20261020T1401_add_stars` needs a decision about `Note.stars`

  |
2 |     Note.stars: {}
  |     ^^^^^^^^^^ decide here
  reason: `Note.stars` is required, and the `Note` records already stored have no value for it.
  next: Set `backfill:` for `Note.stars`, such as `backfill: 1`, then run `jadpo migrate new` to finish the migration (human)
