Some thing wrong with local notification data JSON

I have small issue when I test the local notification on my real devic

The notification work fine but the data can’t be read when i click on notification icon

Here is my code

this.localNotifications.schedule({
  id: 1,
  title: "sending data" ,
  text: "click me to show an alert",
  at: notificationTime,
  data: { event:"show me a msg" }
});

constructor(platform: Platform, ... , public localNotifications: LocalNotifications) {
  platform.ready().then(() => {
     this.localNotifications.on('click', (notification, state) => {
	let notiData = JSON.parse(notification.data);
	if(notiData.event=="show me a msg"){
	   alert("Hi Ali, I received the data :)");
	}
     });
  });
}
