无法将多个元素添加到mongodb数组

我正在尝试使用“ $ push”功能将多个元素输入到mongodb数组中。使用下面的代码,我可以将单个元素添加到数组,但是当我尝试将多个元素添加到数组时,仅添加对象ID,而不会传递。我已经尝试使用POSTMAN尝试许多JSON请求格式,但是似乎都没有用。请帮助我理解问题。

快速路线:

// @route    PUT api/prescription/:patientId
// @desc     Add prescription
// @access   Private

router.post('/:patientId',auth,adminDocguard, async(req,res)=>{
    const {
        mediaction,
        dosage,
        morning,
        evening
    }=req.body;
    var newPrescription={
        mediaction,
        dosage,
        morning,
        evening
    }
    console.log(newPrescription)
    try {
        const patient_profile = await Patient.findOneAndUpdate(

            {patientId:req.params.patientId},
            {"$push":{"prescription":newPrescription}},
            {"upsert":true,"new":true}

          );

          //patient_profile.prescription.unshift(newPrescription);

          await patient_profile.save();
          res.json(patient_profile);

    } catch (err) {
        console.error(err.message);
        res.status(500).send('Server Error');
    }
});


module.exports=router;

Mongo模式

const mongoose= require('mongoose');
autoIncrement = require('mongoose-auto-increment');
const config =require('config');
const db=config.get('mongoURI');

var connection = mongoose.createConnection(db);

autoIncrement.initialize(connection);

const PatientSchema = new mongoose.Schema({
    name:{
        type:String,
        required: true
    },
    phonenumber:{
        type:Number,
        required:true
    },
    date: {
        type: Date,
        default: Date.now
    },
    slider_1:{
        type:Number,
        required: true
    },
    slider_2:{
        type:Number,
        required:true
    },
    slider_3:{
        type:Number,
        required:true
    },
    prescription:[
        {
            mediaction:{
                type:String
            },
            dosage:{
                type:Number
            },
            morning:{
                type:Number
            },
            evening:{
                type:Number
            }
        }
    ]

});
PatientSchema.plugin(autoIncrement.plugin, {
  model:'Patient',
   field:'patientId',
   startAt:1,
   incrementBy:1
});

module.exports=Patient=mongoose.model('patient',PatientSchema);

Json请求

{
 "prescription": [
        {
           "mediaction": "Crocin123",
            "dosage": 200
        },
        {
            "mediaction": "Crocin456",
            "dosage": 200
        }
    ]

}
