tengo un modelo

 const FormDataSchema = new mongoose.Schema({...}) // the Shipping schema const ShippingSchema = new mongoose.Schema({ itemstrackno : { type: String, minlength: [3, "Minimum characters for this field is 3"], maxlength: [100, "Maximum characters for this field is 100"], required: [true, "The Shipped item's tracking number is required"], trim: true, unique: true }, formData: [FormDataSchema] }, {timestamps: true}) const Shipping = mongoose.model("Shipping", ShippingSchema) module.exports = Shipping

mi controlador de correos

 // post a shipment exports.postShipment = async (req, res, next) => { const {itemstrackno, formdata} = req.body try { const trackedItem = await Shipping.findOne({itemstrackno}) if(trackedItem){ return next(new ErrorResponse("An Item with this track number exists", 400)) } const shipment = await Shipping.create({itemstrackno, formdata}) res.status(200).json({ success: true, data: shipment }) } catch (error) { next(error) }

}

Cuando envío una solicitud de publicación con el cartero, aparece el error "Se requiere el número de seguimiento del artículo enviado". ¿Qué estoy haciendo mal?
