【问题描述】：
我们正在为基于 MS Teams 的 BOT 动态渲染自适应卡片。我们面临的问题是卡片在 WebChat 或 Emulator 上呈现良好，但在从 MS Teams 调用时捕获异常。
我们使用了自适应卡片的文档以及设计器，但似乎都不起作用。我们现在很好奇渲染 MS Teams 是否需要一些特殊修复才能工作。根据在线提供的文档，我们已尝试使用“msteams”作为 id。

【问题讨论】：
-
能否请您检查数据是否即将到来？似乎数据为空
-
是的，它适用于 WebChat 和模拟器，但不适用于 MS Teams。我们不明白为什么会这样。事实上，我们已经在模拟器上硬编码了相同的电子邮件地址，它会返回数据。任何见解都会有所帮助
-
能否请您检查委派和应用程序权限？
-
@SashSheen 你能用
displayCardJson的内容更新你的问题吗（你需要一个断点或Console.Write()）？ -
