Anyone know how to deal with "Can't init value outside the transaction" error message?
my intention was to take the entity Lecture with join Educator entity like

return Lecture.findById(id)?.load(Lecture::educator) ?: throw Exception("Lecture not found")

@Transactional annotation is applied to above sentence function and then if i want to use result of above query outside of transactional function. error occurs.
So, i treated this issue with this way, define LectureAggregate ,

data class LectureAggregate(
    val id: Long,
    val createdAt: LocalDateTime,
    val updatedAt: LocalDateTime,
    val name: String,
    val status: LectureStatus,
    val registrationCode: String,
    val educator: EducatorAggregate
) {
    data class EducatorAggregate(
        val id: Long,
        val createdAt: LocalDateTime,
        val updatedAt: LocalDateTime,
        val name: String
    )

    constructor(lecture: Lecture) : this(
        id = lecture.id.value,
        createdAt = lecture.createdAt,
        updatedAt = lecture.updatedAt,
        name = lecture.name,
        status = lecture.status,
        registrationCode = lecture.registrationCode,
        educator = EducatorAggregate(
            id = lecture.educator.id.value,
            createdAt = lecture.educator.createdAt,
            updatedAt = lecture.educator.updatedAt,
            name = lecture.educator.name
        )
    )
}

and assign the result of query to LectureAggregate . In this way, i can avoid the error and can use LectureAggregate freely outside of transaction function. But i think it is temporary solution.
anyone has better solution for this problem?

i followed above instruction to resolve this issue,
but "Can't init value outside the transaction" error keeps occuring.
why keepLoadedReferencesOutOfTransaction options doesn’t work???
for infornation, in the test code i manually connect with databse config option with keepLoadedReferencesOutOfTransaction , it works
