Describe the bug

Archive construct has defaultChild as undefined instead of an instance of CfnArchive

Expected Behavior

I expect archive.node.defaultChild to return instance of CfnArchive, but it is currently undefined

Current Behavior

archive.node.defaultChild returns undefined

Reproduction Steps

const app = new App();
const stack = new Stack(app);
const eventBus = new EventBus(stack, 'eventbus', {
      eventBusName: 'EventBus',
    });
const archive = new Archive(eventBus, 'archive', {
      sourceEventBus: eventBus,
      eventPattern: {
        source: ['test'],
      },
    });
const cfnArchive = archive.node.defaultChild as CfnArchive; // This fails
