Bug: Sending an event with unserializable data to stopped actor throws an error (in development)

[sadn1ck]

XState version

XState version 5

Description

Hey folks! Have made a repro which has all these details -

Essentially -

Sending event to a stopped actor

• with unserializable data → throws
  • due to a JSON.stringify of the entire event object
• serializable data → warns

xstate/packages/core/src/createActor.ts

Lines 657 to 671 in 51d4c4f

	public _send(event: EventFromLogic<TLogic>) {
	if (this._processingStatus === ProcessingStatus.Stopped) {
	// do nothing
	if (isDevelopment) {
	const eventString = JSON.stringify(event);
	console.warn(
	`Event "${event.type}" was sent to stopped actor "${this.id} (${this.sessionId})". This actor has already reached its final state, and will not transition.\nEvent: ${eventString}`
	);
	}
	return;
	}
	this.mailbox.enqueue(event);
	}

Expected result

I expect to not throw.

Actual result

An error was thrown for unserializable data.
