React Native - Expo 48 crash with "Cannot read property '__expo_module_name__' of undefined

[lakardion]

Hello!. I'm getting crashes on Expo 48 latest. I think it has to do with hermes. This is the error:

 ERROR  TypeError: Cannot read property '__expo_module_name__' of undefined, js engine: hermes

This happens at:
node_modules/@pubnub/react-native-chat-components/dist/commonjs/index.js

        if (nativeModule.__expo_module_name__ && reactNative.NativeModules.EXReactNativeEventEmitter) {

Here's a repo I have which is crashing with this error:

https://github.com/lakardion/test-gesture-handler

I tried this out on SDK 47 but it works properly. Seems like this is specific to expo 48 ?

Thanks!

Also experiencing the same issue in new SDK 48 project.

To reproduce:

1. Create a new Expo app with npx create-expo-app <name>
2. Install PubNub libraries
   npx expo install pubnub pubnub-react @pubnub/react-native-chat-components
3. Import anything component from @pubnub/react-native-chat-components into App.js

That's it. Just importing it is enough to cause the error.

This problem should be fixed with the 0.27.0 version of @pubnub/react-native-chat-components which was just released. @lakardion @Justin-Terry @Olli2 please update your dependency and let us know if it worked. At the same time, the package will most likely stop working with Expo versions below 48.

[lakardion]

@Salet Thank you! It is building just fine on my end

[Salet]

Update: please update to 0.27.0 instead, we introduced a problem with sending messages in RN in 0.26.0 by mistake

After installing expo-av, I got the same error.

After installing expo-av, I got the same error.

@OzanOcak hello , Did you solve this problem?

[OzanOcak]

Thank you for asking, I was just able to find out what it was going on after spending so much time on it, all I need was building a new apk for virtual machine. it makes sense actually, sounds are hardware related, there must be os level linking. oh I spent so much time :)

I also got this error when installing expo-ads-admob

[JoaoHamerski]

I was getting this error when trying to install a expo package in a React Native CLI or Expo Bare template, if you aren't using expo blank template, you'll need to configure your app to install expo modules: https://docs.expo.dev/bare/installing-expo-modules/

After that the most important thing is running npm run android or npm run ios to build your native configuration, then you can call your expo package from JavaScript normally.

I also got this error when installing expo-ads-admob

In my case, I didn't get the error if I build the project. Just create a new executable file with the new packages included.

I'm having the same problem with the expo-ads-admob package as well.
But are you saying that we should install "@pubnub/react-native-chat-components": "0.27.0", alongside expo-ads-admob package for the error to be fixed?
Just to be sure. Because i just tried it from my own end and it didn't work.
I'm using: "expo": "~49.0.7",
