query.limit_range
Query limit or page size is below 1.
Area 6, Reads and writes; not declinable; the next step is usually the agent's.

A value's type must keep it at 1 or more too, since PostgreSQL refuses a
negative LIMIT and 0 reads nothing:
type Title = Text { max_length: 80}type ShelfSize = Int { max: 50}entity Book { id: Uuid title: Title}query shelf(size: ShelfSize) -> List<Book> { from: Book order: [Book.title asc] limit: size}
error: `size` can be below 1, so the limit could read nothing --> main.jadpo:17:12 |17 | limit: size | ^^^^ `ShelfSize` has no `min:` reason: `limit:` is how many records come back at most, so it is at least 1, and a value's type must say so with `min: 1` or more, as the built-in `PageSize` (1 to 100) does. next: Give `ShelfSize` `min: 1`, or type the value as `PageSize` (agent) rule: query.limit_range help: https://jadpo.dev/docs/errors/query.limit_rangecheck failed: 1 error, 1 file
