DispatcherError
Dieser Inhalt ist noch nicht in deiner Sprache verfügbar.
Defined in: src/SystemMessages.ts:133
A unit of work scheduled on a dispatcher threw, and supervision was not going to hear about it.
Deliberately not an ActorLifecycleEvent: it is not a
transition in an actor’s life, and its actor may be null — a task
handed straight to dispatcher.execute belongs to no cell. Subscribing
to the lifecycle base must not start delivering failures.
Everything supervision can catch is already caught before it gets here:
a throw out of onReceive goes to the parent’s strategy. What lands on
this channel is what supervision structurally cannot see — a failure in
the machinery around the handler, or in a task the framework never
owned. That makes it low-volume and worth alerting on, which is exactly
why it needed a channel instead of a console line (#410).
