subscriber.run_invalid

Subscriber's run: isn't a call of an action in its own domain.

Area 12, Background work; not declinable; the next step is usually the agent's.

run: calls the action:

example
type Note = Text {    max_length: 200}entity Reminder {    id: Uuid    note: Note    sent: Bool    policy: {        create: [Access.authenticated]        read: [Access.system]        update: [Access.system]    }}type ReminderDue = Event {    reminder_id: Reminder.id}action send_reminder(reminder_id: Reminder.id) fails ReminderNotFound -> Unit {    attempt Reminder.update(reminder_id) {        set: {            sent: true        }    }}subscriber send_due {    on: ReminderDue    run: send_reminder}

error run: send_reminder isn't a call

--> main.jadpo:31:10

   |31 |     run: send_reminder   |          ^^^^^^^^^^^^^ not a call
reason
run: calls one action of the subscriber's own domain, passing the event or its fields; all the logic lives in the action.
next
Write run: <action>(event) (agent)
