App crashes when tapping view in Notification Content Extension

I'm trying to create RichNotification using iOS10's Notification Content Extension, but it's not working.

Only when you tap the view part of RichNotification while the app is not up, it crashes the moment the app starts.
If the app is in the foreground or background, tapping on the view part will work fine.

Also, the notification comes with a custom action, but it works fine in non-starting, foreground, or background.

I believe that the custom task is functioning without any problems, and that even if you tap view with an app in the foreground or background, delete etc. will not fail to be implemented.

When I looked at the log, I found that NSInvalidArgumentException failed only when I tapped view from non-boot state.Is the behavior of only the view tap when the application is not started differently?
If you know how to solve this problem, please let me know.

The following error log

User MyApp[57503]: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'unable to serialize userInfo: Error Domain=NSCocoaErrorDomain Code=3851 "Property list invalid for format: 200 (property lists cannot contain objects of type 'CFNull')" UserInfo={NSDebugDescription=Property list invalid for format: 200 (property lists cannot contain objects of type 'CFNull')}'

Self-resolved.

It seems to occur if there is Null in UserNotification userInfo.
Null was included in the irrelevant data part, so it started working after converting to nil.
