Question

我已经从github.com/VirtoCommerce/vc-storefront-core部署到我的Azure帐户，但在浏览到店面网站时出现以下错误：

启动应用程序时出错。

.NET Core 4.6.26212.01 X86 v4.0.0.0 | Microsoft.AspNetCore.Hosting版本2.0.0-rtm-26452 | Microsoft Windows 10.0.14393 |需要帮忙？

我已确认内容连接字符串正确，App ID和密钥。

查看Azure中的日志流，它是一个500.0错误，它为可能的错误/解决方案提供的链接是to a Microsoft support atticle 它不提供任何Azure信息。

我已经通过Kudu控制台启用了日志记录，而抛出的异常是

`Application startup exception: System.NullReferenceException: Object reference not set to an instance of an object.

尝试对Web App使用远程调试，您可以在其中获取异常以获取有关调试的更多信息。请参阅以下文章：https://docs.microsoft.com/en-us/visualstudio/debugger/remote-debugging-azure以设置远程调试。然后，您可以查看Azure应用服务上的“远程调试ASP.NET核心”部分＆＃34;看看你是否会找到任何有用的信息。
