JSON value '<null>' of type NSNull cannot be converted to NSNumber

Setting a scheduled notification works fine the first time. To update notification time, I’m using the following snippet and it fails with the error shown in the screenshot.

    PushNotification.cancelAllLocalNotifications()
    PushNotification.localNotificationSchedule({
      message: 'My notification message.',
      date,
      repeatType: 'day'
    });

PS. I’m using the master branch.

I came into this issue too and tried to debug it and found that /node_modules/react-native-push-notification/index.js

const iosDetails = {
			fireDate: details.date.toISOString(),
			alertBody: details.message,
			soundName: soundName,
			applicationIconBadgeNumber: parseInt(details.number, 10),
			userInfo: details.userInfo,
			repeatInterval: details.repeatType
		}

in my js I didn’t set number for local notification

  PushNotification.localNotificationSchedule({
                message: "My Notification Message",
                date: date,
             });

so when code execute parseInt(undefined, 10), it will cause an error so I guess that’s why it finally comes out this issue.

Solution1 :Then I tried to add a line of code to check number value as this:

	if(!details.number){
			details.number = 0;
		}
		const iosDetails = {
			fireDate: details.date.toISOString(),
			alertBody: details.message,
			soundName: soundName,
			applicationIconBadgeNumber: parseInt(details.number, 10),
			userInfo: details.userInfo,
			repeatInterval: details.repeatType
		}

Then solve this issue.

Solution2: or just in my js set number a value.

  PushNotification.localNotificationSchedule({
                message: "My Notification Message",
                date: date,
                number: 0
            });

So please have a look if my tips is all right. Thanks @zo0r
