Problem building with expo 53

[zwily]

I just tried upgrading my expo app to expo 53, and ran into a weird issue that I think I may have tracked down to this module somehow, but I don't understand it.

After going through the expo 53 upgrade steps, I regenerated ios app (I use CNG), and when I built started getting this error thrown in the AppDelegate.swift in my app:

Cannot find type 'RCTBridge' in scope

In an effort to figure out what was causing this, I create a brand new Expo 53 app. It has an idential AppDelegate.swift file, but worked fine. So I started adding back in modules from my app to see if any of them caused it to fail. (I would install a module, the run npx expo prebuild --clean and try to build again.)

When I got to the livekit modules, I installed them in this order:

module	success?
@livekit/react-native-webrtc	✅
@livekit/react-native	✅
@livekit/react-native-expo-plugin	❌

I then uninstalled @livekit/react-native-expo-plugin, rebuilt and it worked. Then reinstalled it, and the error came back.

At this point I'm pretty lost. Anyone have a clue what might be happening?

I'm also running into this error in Expo 53

Expo 53 did enable new architecture by default, though I'm not sure if that removes the RCTBridge; regardless this is just the config plugin which is using Expo modules so it should be isolated from that. Not sure where to go from here, so I filed a bug on the Expo repo here:

expo/expo#36595

Error log when compiling on Expo 53:

I don't think this has to do with this being an expo plugin. All my other expo plugins are working fine on 53. I suspect it's one of the pod dependencies somehow causing it.

i have a similar issue, what should i do?

Stay on expo 52 until someone can fix it… it’s likely related to the RN upgrade with expo 53, not expo itself.

same issue, would love a fix soon, expo 53 is dope :)

sadly, even when dowgrading to expo 52 I'm getting the error when building the android app. it says it's an unknown gradle error. i setup everything by the book and still nothing, thanks.

Did you regenerate your native app dirs with prebuild after downgrading?

yes, and if i try to downgrade to expo 51 it brakes a lot of dependencies

I think you’re having a different problem than this bug then. This one only pops up on expo 53, and as far as I know, only on iOS.

Fix has been released through @livekit/react-native version 2.7.4.
