Invariant Violation: new NativeEventEmitter() requires a non-null argument

[remig17]

I am encountering an issue with react-native-push-notification. Despite following the installation and configuration steps, I get the following error when running my React Native app:

ERROR Invariant Violation: new NativeEventEmitter() requires a non-null argument., js engine: hermes

1. Steps to Reproduce:
   Install react-native-push-notification : npm install --save react-native-push-notification

2. Configure react-native-push-notification in the project:

`import PushNotification from "react-native-push-notification";

PushNotification.configure({
  onRegister: function (token) {
    console.log("TOKEN:", token);
  },
  onNotification: function (notification) {
    console.log("NOTIFICATION:", notification);
    notification.finish(PushNotificationIOS.FetchResult.NoData);
  },
  permissions: {
    alert: true,
    badge: true,
    sound: true,
  },
  popInitialNotification: true,
  requestPermissions: true,
});`

3. Run the app on iOS using Xcode.

Expected Behavior
The app should run without errors and handle push notifications as configured.

Actual Behavior
The app crashes with the error:

Invariant Violation: new NativeEventEmitter() requires a non-null argument.

Environment

React Native version: 0.73.6
react-native-push-notification version: 8.1.1
Platform: iOS
Hermes: true

Usually this error is when you are using the new NativeEventEmitter() class to register an event, the instance of this class usually requires the event in question to be taken from react-native's NativeModule.

Try to remove the Pods and Podfile.lock and redo the installation.
