서비스를 등록하지 않은 웹 API asp.net mvc6 앱의 예외

asp.net MVC6 프로젝트에서 작업 중이며 웹 API에 문제가 있습니다. 특정 API를 테스트 할 때 내부 오류 (500 http 응답 코드)가 발생합니다.

조사한 결과 서비스에서 얻으려는 개체를 등록하지 않았다는이 오류를 발견했습니다.

'DotnetProject.BusinessLayer.Implementation.QuerryHandlers.GetTestByIdQueryHandler'유형에 대한 서비스가 등록되지 않았습니다.

문제는 내 컨트롤러가 [FromServices]구문을 사용 하여 IoC 컨테이너에서 특정 개체를 요청하고 해당 서비스를 등록하지 않았다는 예외가 발생한다는 것입니다.

서비스에서 해당 개체를 요청하지 않으면 더 이상 내부 오류가 발생하지 않습니다.

[FromServices]구문이 있는 객체를 요청하는 모든 API 함수에 대해 해당 오류가 발생 합니다. 그래서 문제는 어딘가에 있지만 알아낼 수 없습니다.

내 컨트롤러 클래스는 다음과 같습니다.
