Core Data entity creation fails in remote notification

I've got a simple app delegate method to create a core data object when my push notification arrives. The save() is returning nilError and I can't figure out what I'm doing wrong.

I've verified all the elements of Message have expected data. The attributes are just String, Data, and Date types.

Code Block swiftclass AppDelegate: NSObject, UIApplicationDelegate {
 @Environment(\.managedObjectContext) private var managedObjectContext
  func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
  guard let text = userInfo["text"] as? String,
     let image = userInfo["image"] as? String,
     let url = URL(string: image) else {
   completionHandler(.noData)
   return
  }
  let context = self.managedObjectContext
  URLSession.shared.dataTask(with: url) { data, response, error in
   guard let data = data, error == nil else {
    completionHandler(.failed)
    return
   }
   context.perform {
    let message = Message(context: context)
    message.text = text
    message.image = data
    message.received = Date()
    do {
     try context.save()
     completionHandler(.newData)
    } catch {
     print(error)
     completionHandler(.failed)
    }
   }
  }.resume()
 }
