import Kinvey

class CordInvite : Entity {
 
    dynamic var team: String?
    dynamic var email: String?
    dynamic var invitedBy: String?
    dynamic var invitedOn: Date?
    dynamic var status: Bool = false
 
    override class func collectionName() -> String {
        return "invites"
 }
 
    override func propertyMapping(_ map: Map) {
 super.propertyMapping(map)
 
        team <- ("team", map["team"])
        email <- ("email", map["email"])
        invitedBy <- ("invitedBy", map["invitedBy"])
        invitedOn <- ("invitedOn", map["invitedOn"], KinveyDateTransform())
        status <- ("status", map["status"])
 }
}

Then at some function in our app I have the following code:

 let dataStore = DataStore<CordInvite>.collection(.sync)

            let invite = CordInvite()
            invite.team = user.team
            invite.email = email
            invite.invitedBy = user.userId
            invite.invitedOn = Date()
            invite.status = false

            dataStore.save(invite) { (invite, error) -> Void in
                if let error = error {
                    print(error.localizedDescription)
 }
            }
 
        dataStore.sync() { (count, invites, error) -> Void in
            if let error = error?.first {
 print(error.localizedDescription)
                errorAlert(in: self, baseMessage: "Error Saving Invites", error: error)
                return
 }
 }

The app crashes on the dataStore.sync() with the following exception:

Terminating app due to uncaught exception 'RLMException', reason: 'Invalid value '2017-10-27T20:53:46.219Z' for property 'CordInvite.invitedOn''

I can see however the data gets saved in the collection on Kinvey.  

Can someone tell us how to fix this?  

Thanks!
