Thank you for reporting this issue could you add some reproduction steps? It seems like for some reason it cannot find this method.

Which version of the SDK are you using?

[Chhay67]

I use version 5.0.0, on ios Runner 5.0.1, in production when get notification crashed app due to this error on Ios Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[OSNotificationWillDisplayEvent toJson]: unrecognized selector sent to instance 0x28383caf0'. how to fix this error ?

@emawby firstly, i config get notification work normally, but when click notification navigate to the app it crashed

[emawby]

Is there anything special about the notification you are sending? I have not been able to reproduce this issue yet

[Chhay67]

@emawby I have two project with the same config but one work normally and one get crash on Ios when click notification, and notification are sending the same. Any step for me to try ?

[emawby]

@Chhay67 Thank you for providing this detailed information! Is it possible to share a sample project that is getting the issue or do you have any ideas on how I could setup a project to reproduce the problem? I am not sure what would be causing the iOS bridge to not add the category for the toJson method.

steps reproduce:

• upgrade package to 5.0.1
• setup notification service file.dart as like migration guide
• initialize onesignal on the top route of the project
• generate setup notification on ios like onesignal document
• run app build successful
• when get notification get crash app
• error : OSFlutterNotifications onWillDisplayNofitication -> [self.chanel invokeMethod:@"OneSignal#onWillDisplayNotification" argument:event.toJson]; unecognized selector sent to instance
• can you provide code to catch exception for this line of code for me to test ? @emawby

@Chhay67 I have followed those steps and unfortunately I am still not able to reproduce the issue. I am not sure if you could catch the error without forking the SDK. We could implement a generic catch for this error but that could hide issues in the future
