I have a stable way to reproduce this error.
does access has some kind of a lock? that could explain the null error. when access.transition is called, the previous call is still running and holding the lock.
Correct me if I'm wrong.

the real problem is that I use Future as the effect and
even with .recover(_ => ()) after access.transition, the page is still in a broken state whenever that error occurs.

If I understand correctly, immediatePendingEffects.enqueue(effect) is used by the component.
is there a way to pass sync = true?
