How to do I re-invoke when loading from snapshot?

[alex-chaplianka-dreamed]

I store snapshot when the state changes in an sqlite db.
One of my state has an invoke, and when onDone that moves it to another state.
I want to handle the case where the invoke didn't manage to complete, and the system restarted.

So we load the snapshot from the DB - which seems to have my invoke, but it doesn't run!

This is how I define invoke

const alexProcessingService = () => {};
invoke: [
    {
      id: 'alexProcessor',
      src: fromPromise(alexProcessingService),
      input: ({context}) => ({currentContext: context}),
      onDone: [
        {
          target: DONE
        },
      ]

This is the json value loaded to when the actor starts.

{
  "data": {
    "status": "active",
    "context": {},
    "value": "alex",
    "children": {
      "alexProcessor": { "xstate$$type": 1, "id": "alexProcessor" }
    },
    "historyValue": {},
    "tags": []
  }
}

What I noticed was that when transitioning into the state, I get the function to run, but when loading the snapshot - it does not.

Promises are not reinvoked by default since that may not be desired behavior.

For now, the best approach would be to record and replay events. I'll try to write that up soon, but you can use the inspect API to record events.

@davidkpiano - You mean, when the machine starts, I persiste the events send, and when restoring - I replay them, so that each action and invocation is re-triggered?

Can you clarify what the docs meant by "Invocations will be restarted"? https://stately.ai/docs/persistence

Actions from machine actors will not be re-executed, because they are assumed to have been already executed. However, invocations will be restarted, and spawned actors will be restored recursively.
