afterInsert result fails to retrieve autogenerated datetime

[anthonyma94]

I'm using mariadb v10.4.25 with mysql2 drivers.

I have a class with an afterInsert hook as so:

CREATE TABLE `production_job_status` (
  `id` int(10) UNSIGNED NOT NULL AUTO_INCREMENT,
  `job` varchar(30) NOT NULL,
  `assigned_to` varchar(255) DEFAULT NULL,
  `progress` int(2) DEFAULT 1,
  `order` int(3) DEFAULT NULL,
  `created_at` datetime(6) DEFAULT current_timestamp(6),
  `assigned_at` date DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

export default class ProductionJobStatus {
    id: number;
    job: string;
    assignedTo?: string;
    progress?: number;
    order?: number;
    assignedAt?: Dayjs;
    createdAt: Dayjs;
    static async afterInsert(args) {
        console.log(args.result[0].createdAt); // undefined
    }
}

args.result[0] will retrieve the newly inserted record, including the id, which is auto incremented. However, createdAt is nowhere to be found in the object. How can this be so?
