Adding a default constructor doesn't help , does anyone have any idea how to resolve this ?
This is how my class looks like

data class BreakAnalysis(
	var id: Long,
	val key: BreakAnalysisKey,
	val recGrainId: Int,
	val openDate: LocalDate,
	val closeDate: LocalDate,
	val amount: BigDecimal,
	val isChild: Boolean?,
	var associatedBreakIds: List<Long>?,
	val ttBegin: LocalDateTime,
	val ttEnd: LocalDateTime,
	val systemInsertionRuleId: Int?,
	val groupId: Long,
	val partitionDate: LocalDate,
	val associatedBreakMetaData: Map<String, Any>?,
	val breakMetadata: Map<String, Any>?,
	val recTypeFamilyId: Int,
	val reasonId: Int,
	val ageStartDate: LocalDate,
	val cpidDetails: Map<String, Any?>?,
	val expressionEvaluationDetails: Map<String, Any?>?,
	val grainMap: Map<String, Any?>?,
	val clientUserName: String?,
	val createdBy: String?,
	val updatedBy: String?,
	val previousModificationBy: String?,
	val isWriteOff: Boolean?,
	val comments: String?,
	val clientComments: String?,
	val wireId: Int?,

	val side1Amount: BigDecimal?,
	val side2Amount: BigDecimal?,
	val tick: BigDecimal?,
	val side1TradePrice: BigDecimal?,
	val side2TradePrice: BigDecimal?,
	val adminInvestmentCode: String?,
	val investmentDescription: String?,
	val recStatusId: Int,
	val breakAnalysisWorkflow: BreakAnalysisWorkflow?,
	val attachments: List<Attachment>,
	val workUnitId: Int,
	val workUnitTypeId: Int,
	val contributedToComponentIds: Set<Int>?,
	val reconManifestationId: Long?,

) {
	constructor(): this(-1, BreakAnalysisKey(),-1,LocalDate.now(),LocalDate.now(),

here's a tutorial how to use Jackson with Kotlin, hopefully that helps: https://www.baeldung.com/kotlin/jackson-kotlin

[Stephan Schröder]

otherwise you should know that the Kotlin has its own native solution to serialization that knows about Kotlin stuff like nullability and default values: https://kotlinlang.org/docs/serialization.html#example-json-serialization

[Stephan Schröder]

talking about default values, that probably won't help you in your case but you should know that instead of having an empty constructor providing default values, you could just have default values on each indivitual property:

data class BreakAnalysis(
	var id: Long = -1L,
	val key: BreakAnalysisKey = BreakAnalysisKey(),
    ...
}

your solution seems like the more likely solution to apiece jackson expecting every class having an empty constructor though.
So yeah, check out the tutorial or switch to kotlinx.serialization.
