@sachithras Thank you for reporting do you have any more context about what OneSignal methods are being called leading to this crash? Do you know what the missing UUIDs are about?

We have same crash with a bit more information:

#0 (null) in __exceptionPreprocess ()
#1 (null) in objc_exception_throw ()
#2 (null) in _CFThrowFormattedException ()
#3 (null) in -[__NSPlaceholderDictionary initWithObjects:forKeys:count:].cold.5 ()
#4 (null) in -[__NSPlaceholderDictionary initWithObjects:forKeys:count:] ()
#5 (null) in +[NSDictionary dictionaryWithObjects:forKeys:count:] ()
#6 (null) in +[OneSignalTrackFirebaseAnalytics trackInfluenceOpenEvent] ()
#7 (null) in +[OneSignal registerUserInternal] ()

Looking at this part in trackInfluenceOpenEvent it does not seem safe, dictionary can't hold nil's which is default line above:

NSString *notificationId = [sharedUserDefaults getSavedStringForKey:ONESIGNAL_FB_LAST_NOTIFICATION_ID_RECEIVED defaultValue:nil];
NSString *campaign = [sharedUserDefaults getSavedStringForKey:ONESIGNAL_FB_LAST_GAF_CAMPAIGN_RECEIVED defaultValue:nil];

[self logEventWithName:@"os_notification_influence_open"
            parameters:@{
                @"source": @"OneSignal",
                @"medium": @"notification",
                @"notification_id": notificationId,
                @"campaign": campaign
            }];

Any idea what's going on and how to fix?
The crash happens when opening app from push notification.
