Error: Parameter does not refer to an existing object on the Notification Provider.

[Jim]

       I have added ANCS related functions to my project, but sometimes I get some errors. The error message is as follows: Error: Parameter does not refer to an existing object on the Notification Provider. What could be the cause? What should I do? Thank you!

Hello,

I am faced on with this issue too. In my case this issue occured when the event ID (remove) should be trigered of notifyed message (when i taped on the notifyed message for example in Skype to read it) after that this error output in terminal. With this error i can't handle the event id (remove). Could you please help to resolve this issue?

Hello,

I haven't seen this before. It may be due to new FW update of iOS. Does it happen on multiple iOS versions? What versions have you (both of you) seen this on?

Best regards,

I use iOS 12.2 and SDK 15.3.0

I tested with the same versions, but I couldn't reproduce it. Is it only happening with certain apps? Or does it happen whenever you remove/read a notification from any mobile application?
