Expo: Issue with RNOneSignal.setAppId

[isidor99]

Hi, I am creating an app using Expo bare workflow. I installed this library following documentation and now I constantly get this warning:
[Unhandled promise rejection: TypeError: null is not an object (evaluating 'RNOneSignal.setAppId')]

I tried to reinstall library, created new Onesignal app, created new Firebase app with new server key, but nothing helped me. Does anyone know why this happens?

I created new empty expo bare workflow project and installed this library following official OneSignal documentation and still getting the same issues.

Howdy,
To everyone in this thread, please comment whether you are using Expo bare workflow as well.

I looked into this a bit and did manage to reproduce the issue. It seems that RNOneSignal is undefined at this line here.

I'm not too familiar with Bare workflow but from a quick search it seems like you may need to install something called unimodules: https://docs.expo.io/bare/installing-unimodules/

Please make sure you have those installed as well.

Cheers

The problem was in running the application. When I start app with expo start there is that warning, and OneSignal can't see subscribed user. However, when I start app with npx react-native run-android everything works just fine.
