Omitted or optional field is not present.

Area 2, Values and types; not declinable; the next step is usually the agent's.

example
type TodoView = Output {    pick: [Todo.id, Todo.title]    omit: [Todo.notes]}
text
error: `TodoView` has no field `notes` at this point --> main.jadpo:3:12  |3 |     omit: [Todo.notes]  |            ^^^^^^^^^^ not present  reason: `omit` names a field the lines above bring in, so a typo or a field removed since is caught; none of them brings in `notes`.  next: Remove `Todo.notes` from the list (agent)  rule: type.absent_field  help: https://jadpo.dev/docs/errors/type.absent_fieldcheck failed: 1 error, 2 files
