PowerShell Command 입력 시 에러

Scaffold-DbContext "Host=localhost;Database=mydatabase;Username=myuser;Password=mypassword" Npgsql.EntityFrameworkCore.PostgreSQL -o Models

커맨드 입력 후 Models 폴더가 생성되지 않습니다.

사진은 커맨드 입력 후의 로그이며, 아래는 설치된 패키지 목록입니다.

변경해야되는 DB 이름, user,password 등은 여러번 확인을 해봤습니다 혹시 DB 이름에 _가 포함되면 안되는걸까요?
사진상으로 확인이 힘든 것 같아 아래에 로그 전문 추가하겠습니다.

To protect potentially sensitive information in your connection string, you should move it out of source code. You can avoid scaffolding the connection string by using the Name= syntax to read it from configuration - see https://go.microsoft.com/fwlink/?linkid=2131148. For more guidance on storing connection strings, see https://go.microsoft.com/fwlink/?LinkId=723263.
