我遇到了这个错误：
Unhandled Exception: System.IO.FileNotFoundException: The configuration file 'appsettings.json' was not found and is not optional. The physical path is '/ONEDRIVE/OneDrive - SE/LuloTV/Azure Search/DemoSearchIndexer/bin/Debug/netcoreapp2.2/appsettings.json'.

JSON文件位于源代码目录中，但似乎需要在二进制文件夹中找到该文件。
在使用dotnet run运行应用程序之前，我执行了dotnet build，希望它会将JSON文件复制到输出构建文件夹中，但实际上并没有这样做。
代码如下：
