How to use aggregrate in mongodb to $match _id

Try this

const User = require('User')
const mongoose = require("mongoose");


User.aggregate([
  {
    $match: { _id: new mongoose.Types.ObjectId('560c24b853b558856ef193a3') }
  }
])

const ObjectId = mongoose.Types.ObjectId;
const User = mongoose.model('User')

User.aggregate([
  {
    $match: { _id: ObjectId('560c24b853b558856ef193a3') }
  }
])
