Logging refs does not work in 22.0.0 and 21.0.0 in development mode only in debug mode

[itsmeek]

In the following screenshot, in 22.0.0, console logging the ref causes the app to crash but works fine when in debug mode. In 21.0.0, the app does not crash but nothing shows up in expos console

Can you please clarify what it is about refs that aren't working? Is it just logging them?

Just the logs aren't showing. I changed the title to clarify the issue

Hey guys! The app is crashing and the logs aren't showing for a simple reason — an argument to ref method is a very deep and big cycle object and Expo 25 can't handle those properly. We've fixed this issue on master and the fix will go out in SDK 32. Thank you for your patience. 🙂
