Hey @karthinidc 👋 are you using the React Native CLI or Expo to create your project?

[karthinidc]

@chrisbonifacio - Using React Native CLI to create the project. In the release mode, the App gets crashes.

[chrisbonifacio]

@karthinidc It looks like you tried to share a screenshot of the error but the link is broken in the description. Need more information to try to reproduce this issue.

Also, by release mode do you mean it's crashing only on a physical device? Does it only seem to work in the simulator?

I've never seen this error before when it comes to any of the Amplify libraries. It might be related to this?

https://stackoverflow.com/questions/52269560/react-native-expo-cant-find-variable-self

If you can post the contents of your package.json that might help since the above has to do with Expo but you said you used the RN CLI so maybe the issue has to do with some other dependency.

@chrisbonifacio

It occurs in simulators like screenshots and crashes on a physical device.

@chrisbonifacio Tried "whatwg-fetch": "^3.6.2" but still the error.

If the "aws-amplify": "^4.2.3" package is removed from the package.json then everything is working fine - Package used the error occurs.

@calebpollman Are you familiar with this error when building Amplify apps with the React Native CLI or have some insight? I can only find instances of this issue happening with Expo.

[chrisbonifacio]

@karthinidc Hello! Apologies for the delay. Unfortunately, I have not been able to reproduce this issue. Are you still experiencing the error and in need of assistance?

[karthinidc]

@chrisbonifacio Hi If use the "aws-amplify": "^4.2.3", version in the "react-native": "0.59.9" version project - Still same issue.

[chrisbonifacio]

we noticed that you're using the Auth library but it seems you're missing some important dependencies in your package.json

did you follow the documentation to set up your React Native Amplify project?

Install the necessary dependencies by running the following command:

npm install aws-amplify aws-amplify-react-native amazon-cognito-identity-js @react-native-community/netinfo @react-native-async-storage/async-storage

You will also need to install the pod dependencies for iOS:

npx pod-install
