asp.net-core - 当我尝试在 azure 上运行我的 asp.net core 3.1 应用程序时出现错误 500.30

问题描述

我有一个连接到 sql server 数据库和机密文件的 asp.net core 3.1 应用程序。我可以在本地运行这一切，它可以工作。

我将我的应用程序发布到 Azure，将我的数据库迁移到那里，并创建了一个 Key Vault。所有人都说他们成功了。

当我尝试发布我的应用程序时，它显示数据库和密钥保管库的“已配置”，并且应用程序部署成功。但是，当它将我重定向到应该运行我的应用程序的网站时，我收到 500.30 错误。

这些是我昨天遇到的错误：（我不确定我现在得到了什么，因为我似乎无法在 Azure 上找到找到这些错误的页面，我花了大约 20 分钟寻找它）
