轮播是视觉选择响应，它们需要唯一的密钥才能被识别。因此，您必须为所有轮播项目对象提供选择键。就您而言，似乎您将没有键的对象添加到数组。

请检查以下示例，并尝试根据结构创建对象。

  items: {
    // Add the first item to the carousel
    'SELECTION_KEY_ONE': {
      synonyms: [
        'synonym 1',
        'synonym 2',
        'synonym 3',
      ],
      title: 'Title of First Carousel Item',
      description: 'This is a description of a carousel item.',
      image: new Image({
        url: 'IMG_URL_AOG.com',
        alt: 'Image alternate text',
      }),
    },
    // Add the second item to the carousel
    'SELECTION_KEY_GOOGLE_HOME': {
      synonyms: [
        'Google Home Assistant',
        'Assistant on the Google Home',
    ],
      title: 'Google Home',
      description: 'Google Home is a voice-activated speaker powered by ' +
        'the Google Assistant.',
      image: new Image({
        url: 'IMG_URL_GOOGLE_HOME.com',
        alt: 'Google Home',
      }),
    },
    // Add third item to the carousel
    'SELECTION_KEY_GOOGLE_PIXEL': {
      synonyms: [
        'Google Pixel XL',
        'Pixel',
        'Pixel XL',
      ],
      title: 'Google Pixel',
      description: 'Pixel. Phone by Google.',
      image: new Image({
        url: 'IMG_URL_GOOGLE_PIXEL.com',
        alt: 'Google Pixel',
      }),
    },
  },
}));

您的函数需要重写，以便您的意图处理程序知道该操作是异步的。请注意，还添加了async和await关键字，这些关键字将在给定命令完成时通知解释器。

app.intent('Our Events', async (conv) =>{
  if (!conv.surface.capabilities.has('actions.capability.SCREEN_OUTPUT')) {
  conv.ask('Sorry, try this on a screen device or select the ' +
    'phone surface in the simulator.');
  return;
}
  conv.ask(await getdata());
  conv.ask('Events are here!');
});


async function getdata() {
  let carouselItems ={};
  const snapshot = db.collection('events').get()
  snapshot.forEach(doc=>{
    let itemdetails ={
      title:doc.data().title,
      description:doc.data().info,
      image: new Image({
        url:doc.data().image_url,
        alt:'Image',
      }),
    };
   carouselItems[doc.id]=itemdetails;
   console.log(carouselItems[doc.id]);
  });

  return new Carousel({
    title:'Our Events',
    items: carouselItems,
  });
}
