`query.unknown_field`

Query names a field its entity does not have.

Area 6, Reads and writes; not declinable; the next step is usually the agent's.

example

type Title = Text {    max_length: 80}entity Book {    id: Uuid    title: Title    subtitle: Title?    available: Bool}query books_titled(title: Book.title) -> List<Book> {    from: Book    where: Book.titel == title    order: [Book.id asc]    limit: 20}

jadpo checkcheck failed: 1 error, 1 file

error Book has no field titel

--> main.jadpo:14:17

   |14 |     where: Book.titel == title   |                 ^^^^^ not declared

reason: Book's fields are id, title, subtitle and available. Did you mean title?
next: Use title instead of titel (agent)
rule: query.unknown_field
