null is not an object (evalutating 'u.invocationEventNone') - Instabug + Expo Integration

Question

I'm trying to integrate InstaBug for the first time but keep running into an error at app start-up.

I'm currently running a detached Expo app. I've followed the setup instructions for my app, however, when running, I get the following error:

null is not an object (evaluating 'u.invocationEventNone')

steps to reproduce

# install instabug
$ npm install instabug-reactnative        

# link with RN-cli
$ react-native link instabug-reactnative 

Then initialize InstaBug in App.js

/* ./App.js */
constructor(props) {
  super(props)
  if (Platform.OS == "ios") {
    Instabug.startWithToken('secret_key', [Instabug.invocationEvent.shake]);
  }
}

Add Android Config:

/* android/app/src/main/java/[...]/MainApplication.java */
@Override
protected List<ReactPackage> getPackages() {
  return Arrays.<ReactPackage>asList(
    new MainReactPackage(),
    new RNInstabugReactnativePackage.Builder("secret_key", MainApplication.this)
      .setInvocationEvent("shake")
      .build()
}

What I've tried

I've tried installing it with cocoa pods (and ran pod install) and react-native unlink + manually linking on xCode.

Any help is appreciated
