I am trying to create a Order submission Controller but i want to add a sequence to order_id field. When i try to run getNextSequence function from controller it returns null value and my api call throughs below error
“message”: “Order validation failed: order_id: Please Enter Order Id”

Below is my Counter model Code

`var mongoose = require("mongoose");
var Schema = mongoose.Schema;
var counterSchema = new Schema({
  seq: {
    type: String,
    required: [true, "Please Enter Seq No"],
  },
});
module.exports = mongoose.model("Counter", counterSchema);`

Below is function

`const Counter = require("../models/counterModel");

const getNextSequence = (name) => {
  var ret = Counter.findOneAndUpdate({
    query: { _id: name },
    update: { $inc: { seq: 1 } },
    new: true,
  });
  return ret.seq;
};

module.exports = getNextSequence;`

Below is my Controller code to create a new order

exports.createOrder = catchAsyncErrors(async (req, res, next) => {
  let nextOrderId = getNextSequence("order_id");
  const newreq = {
    order_id: nextOrderId,
    status: req.body.status,
    stage: req.body.stage,
  };

  console.log(newreq);

  const order = await Order.create(newreq);
  res.status(200).json({
    success: true,
    order,
  });
});

in console.log newreq shows like this

{ order_id: undefined, status: 'preparing', stage: 'in oven' }

Somehow function is not passing order_id sequence number e.g. 3,4,5 to Controller.

Tried to find root cause of issue but not successful
