OnTicketValidate

This hook runs immediately after the OnTicketCommands hook and any commands it returned have been applied to the Ticket Actor.

It is the place to enforce invariants that can only be checked once all OnTicketCommands rules have settled, and to either reject the ticket with a validationError effect or auto-fix it by emitting more ticketCommand effects.

Commands returned from this hook are applied to the ticket, but do not re-trigger OnTicketCommands or OnTicketValidate. The hook runs once per message.

Type

{
  hook: 'OnTicketValidate'
  before: Ticket // The ticket before the incoming message commands were applied
  ticket: Ticket // The ticket after OnTicketCommands has run
}
