Mongo Db error validator Error: Masekhta validation failed: _id: Error, expected `_id`

I'm trying to do simple scripts that add an object to Mongo and I get this error Error: Masekhta validation failed: _id: Error, expected _id I don't understand why I think that it's because of the unique validator but mongoose should handle the _id as I know.

First is Schema 

const mongoose = require("mongoose");
const uniqueValidator = require("mongoose-unique-validator");

const Schema = mongoose.Schema;

const masekhtaSchema = new Schema({
  book: { type: String, required: true },
  pesukim: { type: String, required: false },
  selected: { type: Boolean, required: false },
});

masekhtaSchema.plugin(uniqueValidator);

module.exports = mongoose.model("Masekhta", masekhtaSchema);

Script: 

const Masekhta = require("../models/masekhta");

const addMasekhta = async () => {
  const createdMasekhta = new Masekhta({
    book: "test",
    pesukim: "test",
    selected: false,
  });

  try {
    console.log("adding");
    await createdMasekhta.save();
  } catch (err) {
    console.log(err);
  }
};

addMasekhta();
Just to help a bit I have another one that looks pretty the same and it's working so the connection to the DB is clean.

Full Error if needed.

It seems that it comes from mongoose-unique-validator, the issue on github. This is an old package that hasn't been updated in 2 years, so I suggest you avoid it.

I had the same problem, my code worked using

await user.save({validatemodifyedOnly:true})

In Your case,

await createdMasektah.save({validatemodifyedOnly:true})

Hope this can help someone.
