# `migration.out_of_date`

Entities and the latest migration disagree.

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

A project with an entity and no migration yet:


```jadpo
entity Note {
    id: Uuid
    body: Text
}
```

```text
error: No migration creates these entities' tables yet
 --> domains/notes/entities/note.jadpo:1:8
  |
1 | entity Note {
  |        ^^^^ no table yet
  reason: `jadpo check` compares the database schema the entities ask for with the migrations in `database/migrations/`, and there are none: new entity `Note`, new system table for circuit breakers, new system table for deliveries, new system table for handled deliveries, new system table for housekeeping, and 3 more.
  next: Run `jadpo migrate new initial` (agent)
  rule: migration.out_of_date
  help: https://jadpo.dev/docs/errors/migration.out_of_date

check failed: 1 error, 2 files
