In PushHostHandlers.kt

override fun getToken(callback: (Result<String>) -> Unit) {
      FirebaseMessaging.getInstance().token.addOnCompleteListener(OnCompleteListener { task ->
          val fcmToken = task.result
          if (!task.isSuccessful) {
              Log.w(TAG, "Fetching FCM registration token failed", task.exception)
              callback(
                  Result.failure(
                      IllegalStateException(
                          "Fetching FCM registration token failed, but exception was null",
                          task.exception
                      )
                  )
              )
              return@OnCompleteListener
          } else if (fcmToken == null) {
              Log.w(TAG, "FCM token was null")
              callback(Result.failure(IllegalStateException("FCM token was null")))
              return@OnCompleteListener
          }
          // Return latest FCM registration token
          callback(Result.success(fcmToken))
      })
  }

Exception occurred on val fcmToken = task.result, the result should be called when task is successful.
