从BotFramework Adapter在团队中创建消息时出现问题

Question

我正在使用FAQ PLUS Bot模板。
我想发一个帖子到团队频道。可以很好地创建要在团队中发布的消息，但是当代码使用时 BotFrameworkAdapter.CreateConversationAsync()，由于错误的请求，执行失败。我已经搜索了有关它的数据，但是没有与此相关的信息。我在本地和云中进行了测试，但是都失败了。

日志输出为：

Microsoft.Bot.Schema.ErrorResponseException：操作返回了无效的状态码“ BadRequest”

模板为this，找到失败模板的方法为here。

我要在自适应卡中发送的已验证的消息
