Hey Guys.
I think I found a bug on switch node when using it to check if a object has a Key.
Description:
Switch node becomes irresponsive after failing to find a key if parent property does not exist. It throws this error "TypeError: Cannot read property 'hasOwnProperty' of undefined" and Next msg(s) are not analysed and previously corrected filtered msgs no longer passes.
The switch node starts working again only after a full Deploy.
I created a small flow to share.

I can imagine the behavior to be intentional, but for me failing to find parent property should not break the flow
