react-native-exception-handler: Handling exceptions in Android release APK

Hello,

I am able to catch JS as well as Native exceptions in Debug APK. But the exceptions are not caught in Release APK. Can you please suggest I am missing anything? Here is my code:

import { AppRegistry, Alert } from 'react-native';
import App from './App';
import {setJSExceptionHandler, setNativeExceptionHandler} from 'react-native-exception-handler';
import RNRestart from 'react-native-restart';

const reporter = (error) => {
    console.log(error); 
};

const errorHandler = (e, isFatal) => {
    if (isFatal) {
      reporter(e);
      Alert.alert(
          'Unexpected error occurred',
          'Error: ${(isFatal) ? 'Fatal:' : ''} ${e.name} ${e.message}Please close the app and start again!',
        [{
          text: 'Restart',
          onPress: () => {
            RNRestart.Restart();
          }
        }]
      );
    } else {
      console.log(e); 
    }
  };
setJSExceptionHandler(errorHandler, true);
setNativeExceptionHandler((errorString => {
  console.log('Native exception !!!');
}), true);
