SyncKit.CloudKitSynchronizer.SyncError2, recordNotFound

[Mr-ZNN]

I am trying to share my records, but it keeps reporting an error SyncKit.CloudKitSynchronizer.SyncError2.
I located the problem here.

guard let modelAdapter = modelAdapter(for: object),
            let record = modelAdapter.record(for: object) else {
            completion?(nil, CloudKitSynchronizer.SyncError.recordNotFound)
            return
}

fileprivate func modelAdapter(for object: AnyObject) -> ModelAdapter? {
        for modelAdapter in modelAdapters {
            if modelAdapter.record(for: object) != nil {
                return modelAdapter
            }
        }
        return nil
}

this modelAdapters is nil. Why is this？
Below is my model class：

class BaseModel: Object, PrimaryKey {
    /// id
    @objc dynamic var id: String = UUID().uuidString
    
    /// primaryKey
    /// - Returns: primaryKey
    override class func primaryKey() -> String {
        return "id"
    }
}

class EventParent: BaseModel {
    let parents = LinkingObjects(fromType: Event.self, property: "parent")
    @objc dynamic var isSharing: Bool = false
    @objc dynamic var isShared: Bool = false
}

class Event: BaseModel, ParentKey {
    @objc dynamic var parent: EventParent?
    @objc dynamic var name: String = ""
    static func parentKey() -> String {
        return "parent"
    }
}

I seem to have solved the problem.

synchronizer.share(object: eventParent,
                   publicPermission: .readOnly,
                   participants: [],
                   completion: { (share, error) in
    share?[CKShare.SystemFieldKey.title]  = event.name as CKRecordValue
    completionHandler(share, container, error)
})

Before this. The synchronizer is :
lazy var sharedSynchronizer = CloudKitSynchronizer.sharedSynchronizer(containerName: CloudKitToolConfig.containerName, configuration: self.realmConfiguration)
Change to the same as sync is OK：
synchronizer = CloudKitSynchronizer.privateSynchronizer(containerName: CloudKitToolConfig.containerName, configuration: self.realmConfiguration, recordZoneID: CloudKitToolConfig.zoneID)
