发布到 Azure 的 Bot 出现内部服务器错误

Question

所以我一直在使用 Bot Framework SDK v4 创建一个聊天机器人。我一直在本地对其进行测试，它在 Bot Emulator 上运行良好。

我希望能够在 Azure 上托管它并远程访问它，但是当我发布它并且浏览器打开我的 azurewebsites.net 网页时，该页面只显示一个错误提示 启动应用程序时发生错误.

当我查看控制台检查错误时，有 2 个资源请求加载失败：

Failed to load resource: the server responded with a status of 500 (Internal Server Error) /favicon.ico:1 
Failed to load resource: the server responded with a status of 500 (Internal Server Error) (index):1

这是我第一次使用 Azure 或向 Azure 发布内容，所以我对它并不太熟悉。据我所知，我的本地目录中没有这些名称下的任何文件，我不确定如何解决这个问题。

关于造成这种情况的原因是什么？如果需要，我可以提供更多代码。

编辑 我从 Application Insights 和 Kudu 收集的更多信息。

当尝试使用“测试 Web 应用程序”向 Azure 中的机器人发送消息时，我收到了以下异常：

此外，通过检查 Kudu 中的日志，该 html 对可能的原因进行了描述：

<fieldset>
<h4>Most likely causes:</h4>
<ul>
    <li>IIS received the request; however, an internal error occurred during the processing of the request. The
        root cause of this error depends on which module handles the request and what was happening in the worker
        process when this error occurred.</li>
    <li>IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS
        permissions are set incorrectly.</li>
    <li>IIS was not able to process configuration for the Web site or application.</li>
    <li>The authenticated user does not have permission to use this DLL.</li>
    <li>The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.</li>
</ul>

Answer 1

System.IO.FileNotFoundException: Could not find file 'D:\home\site\wwwroot\Chatbot.bot'.

您是如何将项目部署到 Azure 的？您的“Chatbot.bot”文件似乎没有部署到 wwwroot，这是必需的，并且可以包含机器人特定设置，例如应用程序 ID 和密码。

相关 StackOverflow 问题中的 answer 描述了如何在 Visual Studio 中部署后上传 .bot 文件，但您也可以手动将文件上传到 wwwroot。
