HibernateException: Flush during cascade is dangerous during recordTransaction - corda

Question

I am testing Corda 4.1 Open Source with Zone Constraints and I have 4 nodes which is Node A, Node B, Node C and Notary (the Notary is a CE version of Corda 4.1)
I run the IssueFlow to create StateA from Node B to Node A.
And in the IssueFlow.Responder after commit the transaction Node A subFlow a TestFlow to update the StateA which will add Node C to the participants of StateA.
This is the code in IssueFlow.Responder
#InitiatedBy(IssueFlow.Initiator::class)
class Responder(val otherFlow: FlowSession) : FlowLogic<SignedTransaction>() {
#Suspendable
override fun call(): SignedTransaction {
val flow = object : SignTransactionFlow(otherFlow) {
#Suspendable
override fun checkTransaction(stx: SignedTransaction) {
// Custom validation here
}
}
val stx = subFlow(flow)
val waitForLedgerCommit = subFlow(ReceiveFinalityFlow(otherFlow, stx.id))
executableAfterCommit(waitForLedgerCommit)
return waitForLedgerCommit
}
#Suspendable
private fun executableAfterCommit(stx: SignedTransaction) {
val listOfStateA = stx.tx.outputsOfType<StateA>()
require(listOfStateA.size == 1) { "Only one document of StateA is allowed in the transaction." }
val stateA = listOfStateA.single()
subFlow(TestFlow.Initiator(listOf(stateA.linearId.id.toString())))
}
}
In TestFlow I will update some information for StateA and add Node C as another participant but I want only NodeA and NodeB to sign.
The code as follow:
object TestFlow {
#InitiatingFlow
#StartableByRPC
class Initiator(private val linearId: String) : FlowLogic<SignedTransaction>() {
override val progressTracker: ProgressTracker()
val window by lazy { TimeWindow.withTolerance(currentClock.instant(), 30.minutes) }
#Suspendable
override fun call(): SignedTransaction {
val stx = collectSignatures(verifyAndSign(build()))
val sessions = transaction.sessionsOfParticipants()
return subFlow(FinalityFlow(stx, sessions))
}
private fun build(): TransactionBuilder {
val statesIn = queryByLinear(listOf(linearId.toUUID())).single()
val stateOut = stateIn.changeData("field1").addParticipants(NodeC)
val result = TransactionBuilder(firstNotary).apply {
// Add inputs
withItems(statesIn)
// Add outputs
withItems(StateAndContract(stateOut, StateAContract.CONTRACT_ID))
// Signer only NodeA and NodeB
val listOfSigner = listOf(statesIn.state.data, stateOut)
.selectKeysOf(addNodeA = true, addNodeB = true)
.toList()
// Add commands
addCommand(StateAContract.Commands.Test(), listOfSigner)
setTimeWindow(window)
}
return result.toLedgerTransaction(serviceHub)
}
private fun verifyAndSign(transaction: TransactionBuilder): SignedTransaction {
transaction.verify(serviceHub)
return serviceHub.signInitialTransaction(transaction)
}
#Suspendable
private fun collectSignatures(transaction: SignedTransaction): SignedTransaction {
val signers = excludeNotary(groupPublicKeysByWellKnownParty(serviceHub, transaction.getMissingSigners()), transaction).map { it.key }
return subFlow(CollectSignatureInitiator(transaction, signers))
}
}
#InitiatedBy(Initiator::class)
class Responder(private val otherFlow: FlowSession) : FlowLogic<SignedTransaction>() {
#Suspendable
override fun call(): SignedTransaction {
return subFlow(ReceiveFinalityFlow(otherFlow))
}
}
/**
* Collect signature initiating flow
*/
#InitiatingFlow
class CollectSignatureInitiator(private val transaction: SignedTransaction, private val signers: List<Party>) : FlowLogic<SignedTransaction>() {
#Suspendable
override fun call(): SignedTransaction {
val sessions = signers.map { initiateFlow(it) }
return subFlow(CollectSignaturesFlow(transaction, sessions))
}
}
/**
* Collect signature responder flow
*/
#InitiatedBy(CollectSignatureInitiator::class)
class CollectSignatureResponder(private val session: FlowSession) : FlowLogic<SignedTransaction>() {
#Suspendable
override fun call(): SignedTransaction {
return subFlow(object : SignTransactionFlow(session) {
override fun checkTransaction(stx: SignedTransaction) {
subFlow(ValidateDocument(session, stx))
return
}
})
}
}
}
and TestFlow throw an error in Node C as follow:

Now what I'm doing to solve this problem is I went to onchain database and truncate the following table
- node_info_party_cert
- node_link_nodeinfo_party
- node_info_hosts
- node_infos
After truncate these table I restart Node C then let it resume from node checkpoints and everything works.
Sometimes the error happens on Both Node B and Node C.
I'm using the same code and test in the CE environment but I didn't found this error.
The question is
What is the root cause of this error?
What was Corda is trying to do when recordTransactions?
What is the proper way to solve this problem?

Answer 1

This issue is resolved with the latest version of Corda OS 4.3.
You can get update your dependencies at build.gradle, and point it to newer version of Corda.
