出现在Google Assistant应用程序中拨打电话的问题

Question

我尝试在基本卡中实现按钮，但出现错误

API版本2：无法解析带有'INVALID_ARGUMENT'错误的JSON响应字符串：“（expected_inputs [0] .input_prompt.rich_initial_prompt.items [1] .basic_card.buttons [0] .open_url_action）版本：找不到字段。” HTTP状态码：200。

 conv.ask(new BasicCard({
    text: `This is a basic card.  Text in a basic card can include "quotes" and`,
    subtitle: 'This is a subtitle',

    buttons: [
     {
      "title": "Call",
      "openUrlAction": {
          "url": "tel:[phone]",
          "androidApp": {
              "packageName": "com.android.phone"
          },
          "versions": []
       }
    },
   ],
    "formattedText": "Some text",
    image: new Image({
      url: 'https://storage.googleapis.com/actionsresources/logo_assistant_2x_64dp.png',
      alt: 'Image alternate text',
    }),
    "title": "Card Title"
  }));

并且我尝试了所有方法在按钮数组中添加另一个空对象，也出现相同的错误：

buttons: [
     {
      "title": "Call",
      "openUrlAction": {
          "url": "tel:[phone]",
          "androidApp": {
              "packageName": "com.android.phone"
          },
          "versions": []
       }
    },
  {}
   ],

以下尝试的代码出现错误：

expected_inputs [0] .input_prompt.rich_initial_prompt.items [1] .basic_card.buttons [0] .open_url_action：协议必须为http或https。

buttons: new Button({
      "title": "button text",
      'url': "tel:[phone]",
      "androidApp": {
        "packageName": "com.android.phone"
      }
})

在动作控制台模拟器中获得响应：

"buttons": [
                  {
                    "title": "button text",
                    "openUrlAction": {
                      "url": "tel:[phone]"
                    }
                  }
           ]
