서버 실행 후 http://localhost:3002/api/users URL로 빈 값을 POST로 보내면 콘솔창에 400 이메일이 없습니다. 라는 문구가 뜬 이후에

        if (!metadata) throw new EntityMetadataNotFoundError(target)

위와 같이 EntityMetadataNotFoundError에러가 발생합니다. DB 커넥션 부분도 확인해보고, entities 부분이 문제인가 싶어 아래와 같이 변경도 해보았지만

TypeOrmModule.forRoot({
      entities: ['./entities/*.{js,ts}'],
  ],

해결되지 않아 질문드립니다.

추가적으로 \data-source\DataSource.ts 부분과

\repository\Repository.ts부분은 실제 디렉토리에 없는 것들인데 왜 뜨는지도 모르겠습니다.

해결 방법이 있을까요?
