react-native-simple-openvpn not connecting.

Bug description:

When I try to connect my react native app to the vpn server I get this error: TypeError: Cannot read property 'connect' of null. The vpn is active on aws cloud service.

Expected behavior:

The app is very basic. I did not add anything to it yet first I wanted to check if the vpn was working or not.I added this code to my app,tsx:

/**
 * Sample React Native App
 * https://github.com/facebook/react-native
 *
 * @format
 */

import React, {useEffect} from 'react';
import {
  Button,
  Platform,
  SafeAreaView,
  StatusBar,
  Text,
  useColorScheme,
} from 'react-native';
import RNSimpleOpenvpn, {
  addVpnStateListener,
  removeVpnStateListener,
} from 'react-native-simple-openvpn';

import {Colors} from 'react-native/Libraries/NewAppScreen';

const isIPhone = Platform.OS === 'ios';

function App(): JSX.Element {
  useEffect(() => {
    let isMounted = true;

    async function observeVpn() {
      if (isIPhone) {
        await RNSimpleOpenvpn.observeState();
      }

      addVpnStateListener(e => {
        // Handle VPN state changes
        console.log(e);
      });
    }

    if (isMounted) {
      observeVpn();
    }

    return () => {
      isMounted = false;

      async function cleanup() {
        if (isIPhone) {
          await RNSimpleOpenvpn.stopObserveState();
        }

        removeVpnStateListener();
      }

      cleanup();
    };
  }, []);

  async function startOvpn() {
    try {
      await RNSimpleOpenvpn.connect({
       remoteAddress: '16.16.67.136 943',
        ovpnFileName: 'client',
        assetsPath: 'ovpn/',
        providerBundleIdentifier: 'com.example.RNSimpleOvpnTest.NEOpenVPN',
        localizedDescription: 'RNSimpleOvpn',
        username: '<username>',
        password: '<password>',
      });
    } catch (error) {
      console.log(error);
    }
  }

  async function stopOvpn() {
    try {
      await RNSimpleOpenvpn.disconnect();
    } catch (error) {
      console.log(error);
    }
  }

  const isDarkMode = useColorScheme() === 'dark';

  const backgroundStyle = {
    backgroundColor: isDarkMode ? Colors.darker : Colors.lighter,
  };

  return (
    <SafeAreaView style={backgroundStyle}>
      <StatusBar
        barStyle={isDarkMode ? 'light-content' : 'dark-content'}
        backgroundColor={backgroundStyle.backgroundColor}
      />
      <Text>Hello</Text>
      <Button onPress={startOvpn} title="Start Vpn" />
      <Button onPress={stopOvpn} title="Stop Vpn" />
    </SafeAreaView>
  );
}

export default App;

I had the same error and after investigating native logs in LogCat I found that the original error was OpenVPNThread Got java.lang.NullPointerException: Attempt to invoke virtual method 'void java.lang.Process.destroy()' on a null object reference I/VpnState: NOPROCESS No process running. LEVEL_NOTCONNECTED

I added android:extractNativeLibs="true" to <application> like this

<application ... android:extractNativeLibs="true">

in android/app/src/main/AndroidManifest.xml and it worked! The error has gone
