ASP.NET Core Web API 不适用于 Azure

我对这个主题很陌生，但我已经使用 .Net 5 编写了一个 ASP.NET Core Web API。这个 API 只是读取和写入 Azure DB 的值。它在我的机器上运行良好，但在上传/发布到 Azure 后，我收到“500 - 内部服务器错误”

{ 
"statusCode": 500, 
"message": "Internal server error", 
"activityId": "15ed7068-cb40-4e79-8205-cc4c6d4be8be" 
}

我已经按照 Microsoft Doc 发布我的 API：https ://docs.microsoft.com/en-us/aspnet/core/tutorials/publish-to-azure-api-management-using-vs?view = aspnetcore- 5.0

一旦我到了步骤https://docs.microsoft.com/en-us/aspnet/core/tutorials/publish-to-azure-api-management-using-vs?view=aspnetcore-5.0它就不起作用了。这是跟踪：

我已经尝试制作一个全新的项目并重新发布该项目，但没有成功。
