Bug on swipeRefreshLayout

[Ogiwara-CostlierRain464]

When I write like this,

override fun view() {
                frameLayout {
                    size(FILL,FILL)
                    swipeRefreshLayout {
                        size(FILL,FILL)
                    }
                }
}

Error will occur like this.

E/InputEventReceiver: Exception dispatching input event.
E/MessageQueue-JNI: Exception in MessageQueue callback: handleReceiveCallback
E/MessageQueue-JNI: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.view.View.canScrollVertically(int)' on a null object reference
