无法使用 Node JS 渲染自适应卡片

如何解决无法使用 Node JS 渲染自适应卡片

我正在尝试在 Node.js 上使用 JavaScript 呈现可操作的消息。卡片有效载荷直接从 https://messagecardplayground.azurewebsites.net/ 中选取：

                                                ]
                                            }
                                        }
                                    ]
                                }
                            ]
                        }
                    ]
                }
            ]
        }
    ]
}

我正在使用 https://docs.microsoft.com/en-us/adaptive-cards/sdk/rendering-cards/javascript/render-a-card 中的示例代码。

我得到的输出是：

<div class="ac-container ac-adaptiveCard" style="display: flex; flex-direction: column; justify-content: flex-start; box-sizing: border-box; flex: 0 0 auto; padding: 15px 15px 15px 15px; margin: 0px 0px 0px 0px;" tabindex="0"><div class="ac-container" style="display: flex; flex-direction: column; justify-content: flex-start; box-sizing: border-box; flex: 0 0 auto; padding: 0px 0px 0px 0px; margin: 0px 0px 0px 0px;"></div></div>

这只是呈现一个空的身体。

你能告诉我我在这里做错了什么吗？我们是否有可以从中汲取灵感的示例工作代码？

非常感谢您在这里帮助我。
