Необработанное исключение типа «System.AggregateException» произошло в Microsoft.Extensions.DependencyInjection.dll: ⇐ C#

[Anonymous]

Я перенес основной проект asp.net с версии 2.2 на 3.1. Я добавил все зависимости и компоненты, связанные с докером. Компилируется нормально, но при запуске проекта я получаю следующую ошибку:

Я следовал рекомендациям шаблонов, упомянутым по адресу:
https://github.com/Dotnet-Boxed/Templat ... cs/GraphQL. md

На основе вышеизложенного я создал POC, который работает нормально, но не вышеупомянутый код.

Может кто-нибудь поможет мне решить эту проблему, предоставив свои руководство
