I migrated a asp.net core project from version 2.2 to 3.1. I have added all the dependencies and docker related components. It is compiling fine but on running the project I am getting the below mentioned error:
Exception thrown: 'System.AggregateException' in Microsoft.Extensions.DependencyInjection.dll An unhandled exception of type 'System.AggregateException' occurred in Microsoft.Extensions.DependencyInjection.dll: 'Some services are not able to be constructed' Stack trace: at Microsoft.Extensions.DependencyInjection.ServiceProvider..ctor(IEnumerable

I followed the guidelines of Templates mentioned at: https://github.com/Dotnet-Boxed/Templates/blob/master/Docs/GraphQL.md
Based on the above I created a POC which works fine but not the above mentioned code.
Can anyone help me to fix this issue by providing their guidance
