[英]IdentityServer4 Fails to start in Azure error Cannot create instance of type 'System.String' because it is missing a public parameterless constructor
Probably something really dumb that I have done, however I have a project built on ABP.IO (.Net6.0 ABP 5.0.0-rc1) I have deployed the HttpApi.Host project to an Azure Web App, using AzureDevops pipelines for the构建和发布。
但是 HttpApi.Host 无法从以下登录日志文件开始：（根据我的调查，它发生在 program.cs 中的 app.UseIdentityServer 上）它仅在 Azure 上失败，如果我启动 HttpApi.Host 项目在本地它运行良好，我得到了 swagger ui。 但在 Azure 中，它无法启动，并且在尝试浏览网站时出现“HTTP 错误 500.30 - ASP.NET 核心应用程序无法启动”。
