I have update on_pre_post_update function at Util_AttachToActions.php and the error is gone (row 63):

public function on_pre_post_update( $post_id, $post = null ) {
		$post = get_post( $post_id );

		// if attachment changed - parent post has to be flushed
		// since there are usually attachments content like title
		// on the page (gallery).
		if ( 'attachment' === $post->post_type ) {
			$post_id = $post->post_parent;
			$post    = get_post( $post_id );
		}

		if ( 'draft' !== $post->post_status ) {
			return;
		}

		$cacheflush = Dispatcher::component( 'CacheFlush' );
		$cacheflush->flush_post( $post_id );
	}

p.s. I know it’s a dummy code, but it’s work) lol
