public Page<AuthInfoDto> searchList(AuthSearchRequestDto requestDto) {

	JPAQuery<AuthInfoDto> query = queryFactory.select(Projections.fields(
		AuthInfoDto.class,
		member.email,
		member.memberStatus.as("status"),
		member.createdAt
	)).from(member)
	.where(searchCondition(requestDto)); // 검색 조건 설정
	long totalCount = query.fetchCount();
	List<AuthInfoDto> authInfoList = this.getQuerydsl().applyPagination(requestDto.getPageable(), query).fetch();

	return new PageImpl<>(authInfoList, requestDto.getPageable(), totalCount);
}

사용자 정보를 Pagination해서 출력하게끔 하려고 합니다.

문제가 되는 부분은

List<AuthInfoDto> authInfoList = this.getQuerydsl().applyPagination(requestDto.getPageable(), query).fetch();

해당 코드 부분인데 단순히 query.fetch()를 해서 List를 추출하는 것은 되지만 Pagination을 적용하고자 하면 에러가 납니다.

org.hibernate.query.SemanticException: Could not interpret path expression 'member.createdAt'

에러 내용은 위와 같습니다.

QueryDSL 관련 gradle 정보도 같이 첨부합니다.

// QueryDSL
implementation 'com.querydsl:querydsl-core:5.0.0'
implementation 'com.querydsl:querydsl-jpa:5.0.0:jakarta'
implementation 'com.querydsl:querydsl-apt:5.0.0:jakarta'

혹시 뭐가 문제일까요?? 도와주세요.
