On <StrictMode> the re-render is causing the reference returned by system.get to be undefined on the body of a fromCallback logic function:
Expected result
On <StrictMode> , system.get('feedback') should consistently return a reference to the feedbackActor instead of undefined
Actual result
If the machine spawning the reference is not the machine being accessed by system.get.
In this scenario I got 3 actors:
root (machine)
alert (fromCallback)
feedback (machine)
If root spawns both actors then whenever alert function callback is called the second time (due to <StrictMode> re-rendering) then system.get('feedback') will return undefined ❌, while system.get('root') returns the actor reference ✅.
If root spawns feedback and feedback spawns alert then the problem is solved. ✅
