iOS Sales force CHAT SDK crash when the sales force agent accepts the call.
I'm using the SF SDK version: 224.0.2. The app is breaking in Urban Airship side. Not clear to me why this is happening. It looks like Urban Airship is trying to process a push notification without data, just after the SF agent accepts the chat request on the web.
The error: Thread 1: Swift runtime failure: Unexpectedly found nil while unwrapping an Optional value
