Crash with "TypeError: Cannot add property parent, object is not extensible" #2

Love the look of this, but I can't try it out in our production app because I'm getting this crash on one of our primary machines. Believe the error is coming from here

The child it's crashing on is a spawned callback. Let me know if you need any more info to repro.

rlaffers commented 2 years ago

More info is needed indeed. What does the error say? Can you make a minimal repro on Codesandbox?

UberMouse commented 2 years ago

Yep, looks the problem is with an interaction with @xstate/immer, worked fine with the normal assign from xstate but crashed when I switched to the assign from @xstate/immer
