更新团队清单 - 未设置对象引用

Question

我们目前正在构建一个 MS Teams 应用程序，我们正处于 POC 阶段。

当使用 Visual studio 中的菜单使用清单中的最新更改更新清单时，出现以下错误。 项目 -> TeamsFx -> 更新团队清单

System.NullReferenceException: Object reference not set to an instance of an object.
   at TeamsFx.VisualStudio.Definitions.AppDefinitionBot.FromAppManifestBot(AppManifestBot appManifestBot)
   at TeamsFx.VisualStudio.Commands.TeamsAppManifest.<>c.<MergeIntoTeamsAppDefinitionAsync>b__18_2(AppManifestBot bot)
   at System.Linq.Enumerable.WhereSelectListIterator`2.MoveNext()
   at System.Collections.Generic.List`1..ctor(IEnumerable`1 collection)
   at System.Linq.Enumerable.ToList[TSource](IEnumerable`1 source)
   at TeamsFx.VisualStudio.Commands.TeamsAppManifest.<MergeIntoTeamsAppDefinitionAsync>d__18.MoveNext()

bot定义如下：

  "bots": [
    {
      "botId": "someId",
      "needsChannelSelector": false,
      "isNotificationOnly": false,
      "scopes": [
        "team",
        "personal",
        "groupchat"
      ]
    }
  ],

然后我们只有 composeExtensions 来展示卡片，用 2 个简单的例子来测试它是如何工作的。

  "composeExtensions": [
    {
      "botId": "someId",
      "canUpdateConfiguration": true,
      "commands": [
        {
          "id": "createCard",
          "type": "action",
          "context": [ "message" ],
          "description": "Command to run action to create a Card from Compose Box",
          "title": "Create Card",
          "parameters": [
            {
              "name": "title",
              "title": "Card title",
              "description": "Title for the card",
              "inputType": "text"
            },
            {
              "name": "subTitle",
              "title": "Subtitle",
              "description": "Subtitle for the card",
              "inputType": "text"
            },
            {
              "name": "text",
              "title": "Text",
              "description": "Text for the card",
              "inputType": "textarea"
            }
          ]
        },
        {
          "id": "createAdaptiveCard",
          "type": "action",
          "context": [ "message" ],
          "description": "Command to run action to create a Card from Compose Box",
          "title": "Adaptive Card",
          "parameters": [
            {
              "name": "title",
              "title": "Name",
              "description": "Name of the User",
              "inputType": "text"
            },
            {
              "name": "subTitle",
              "title": "Designation",
              "description": "Designation of the User",
              "inputType": "text"
            },
            {
              "name": "text",
              "title": "Description",
              "description": "Description",
              "inputType": "textarea"
            }
          ]
        }
      ]
    }
  ],

最终结果是 MS Teams 中的应用运行它没有引入最新的更改。

TeamFx 验证通过且没有错误。我的假设是清单文件中有问题，尽管我找不到任何突出的内容。

谁能告诉他们以前是否遇到过这个问题以及如何解决？

提前致谢。

Answer 1

我发现解决方案是在清单文件的机器人部分中包含以下内容：

"commandLists": []"

如果未定义，则抛出异常。已定义，但只有一个空列表，已解决。
