mongoose-beautiful-unique-validation Custom message not working

Hello,

I have the following schema:

const mongoose = require('mongoose');
const beautifyUnique = require('mongoose-beautiful-unique-validation');

const UserSchema = new mongoose.Schema({
  email: {
    type: String,
    lowercase: true,
    required: true,
    unique: 'A user with that e-mail already exists',
  },
  firstName: {
    type: String,
    required: true,
  },
  lastName: {
    type: String,
    required: true,
  },
});

UserSchema.plugin(beautifyUnique);

module.exports = mongoose.model('User', UserSchema, 'Users');

When I try to create a document with a duplicate e-mail, I don't get the custom message, instead I only get the following:

{ ValidationError: Validation failed
    at ValidationError.inspect (node_modules/mongoose/lib/error/validation.js:56:24)

  errors: {},
  _message: 'Validation failed',
  name: 'ValidationError' }

I am using mongoose 5.0.13 and mongoose-beautiful-unique-validation 7.1.1.

Am I missing anything?

Seems there is a problem with the regexp... :(

Hello! Is this problem fixed? I have a similar situation, but the output differs a little:

{
    "errors": {},
    "_message": "Validation failed",
    "message": "Validation failed",
    "name": "ValidationError"
}

My schema looks like this:

const schema = new mongoose.Schema({
    // other properties
    email: { type: String, required: true, unique: 'Email must be unique: ({VALUE})' },
});

schema.plugin(beautifyUnique);

I did tries with different version of this plugin and the issue seems to be present in mongo version 3.6 to up, with mongo 3.4 works!! but my solution was drop the plugin and focus in parse the error throwed by mongodb and so base on the example provide in the mongoosejs 5 website i did this code mimic the exact same response of this plugin.

UsersSchema.post("save", function (error, doc, next) {
  let duplicateError = error.name === "MongoError" && error.code === 11000;
  if (duplicateError) {
    let result = {
      name: "ValidationError",
      message: "Model validation failed",
      errors: {}
    }
    //Object.keys(this._doc) = ["email", "name", "password", ......]
    Object.keys(this._doc).forEach(path => {
      let isDuplicate = error.errmsg.includes(`$${path}_1`);//match with $email_1
      //Check if any attribute of the document is included in the error message as an unique field example:
      //11000 E11000 duplicate key error index: mydb.users.$email_1  dup key: { : "[email protected]" }
      if (isDuplicate) {
        let value = this._doc[path];
        result.errors[path] = {
          name: "ValidatorError",
          kind: "unique",
          message: `Path ${path} (${value}) is not unique.`,
          path,
          value
        }
      }
    })    
    next(result);
  } else {
    next()
  }
})

So as long mongoose return the error name as MongoError an the code as 11000 for duplicate values it should work in any version.

Having the same problem here in my tests using mongodb-memory-server at least. Instead of returning my unique message it just returns.

Mongoose version: 5.4.10
