Tiene este modelo

 export const IEventSchema = new mongoose.Schema<IEventBase>({ type: {type: String, enum: EventType, required: true}, date: {type: Number, required: true}, title: {type: String}, description: {type: String}, notifiedUsers: [ { type: Schema.Types.ObjectId, ref: 'User', default: {} } ], unnotifiedUsers: [ { type: Schema.Types.ObjectId, ref: 'User', default: {} } ], });

Quiero mover el contenido de la matriz de usuarios notificados a usuarios no notificados, dentro del método findByIdAndUpdate del enrutador.

 router.put('/delay/:id', async (req: Request, res: Response) => { try { await Event.findByIdAndUpdate(req.params.id, { $set: {date: req.body.date}, // Write Here } ); res.status(200).json(`Event delayed to ${req.body.date}`); } catch (e: any) { console.log(e); } });

 $addToSet: {unnotifiedUsers: {$each: 'notifiedUsers'}} // Does not working
