Corda 4 tutorial has syntax error

[fuxiocteract]

in CarFlow.kt

The following code doesn't work with current dependency for CollectSignatureFlow, FinalityFlow and ReceiveFinalityFlow, what should they actually be?

in CarFlow.kt, in CarIssueInitiator class, the tutorial has:
val sessions = (carState.participants - ourIdentity).map { initiateFlow(it as Party) } val stx = subFlow(CollectSignaturesFlow(tx, sessions)) return subFlow(FinalityFlow(stx, sessions))
The last 2 lines has syntax error, CollectSignaturesFlow does not have an implementation taking a list of FlowSession, and FinalityFlow need to pass a ProgressTracker it seems, or convert sessions to Array

in CarIssueResponder class,
the tutorial has
return subFlow(ReceiveFinalityFlow(counterpartySession, txWeJustSignedId))
ReceiveFinalityFlow implementation does not has a version taking a FlowLogic as param.
