Mongoose deprecation warning for Query.prototype.stream()

Which version of mongoose do you use?

With >5.0.0 this message should disappear code: https://github.com/jbdemonte/mongoose-elasticsearch-xp/blob/master/lib/index.js#L341

Oh, that seems to be the problem. I'm currently using mongoose 4.9.0 because of which that depreciation warning might have come up.

I'll change the version and update it here

@nodkz Can you please help me out on what to use as a replacement for .on()

i.e. previously, we have been using Model.on('es-bulk-error', function( err ){ console.log('Error : ', err) }) which is showing another warning,

UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): TypeError: Cannot read property 'on' of undefined

[nodkz]

Provide detailed console output for your rejection.

For this, you need to add following code to your app:

process.on('unhandledRejection', error => {
  console.log('unhandledRejection');
  console.dir(error);
});

This is what it shows on type error,

It may be a problem with wrong bulker option which you provide for mongoose-elasticsearch-xp: https://github.com/jbdemonte/mongoose-elasticsearch-xp/blob/master/lib/index.js#L343

[yvsssantosh]

Yeah, I thought the same, this is actually my models.py

'use strict'

const Joi = require('joi')
const Mongoose = require('mongoose')
const Joigoose = require('joigoose')(Mongoose)

const MongoosasticXP = require('mongoose-elasticsearch-xp')

let SampleJoi = Joi.object().keys({
  //...
  //...
  // Some schema
})

let mongooseSampleSchema = Joigoose.convert(SampleJoi)

let mongooseSampleMiddlewareSchema = new Mongoose.Schema(mongooseSampleSchema)

//
// Some config for elasticsearch
//

let SampleDb = Mongoose.model('Sample', mongooseSampleMiddlewareSchema)

SampleDb.on('es-bulk-error', function (err) {
  console.log(err)
  throw Error(err)
})

SampleDb.esSynchronize().then(function (response) { // Here is where the error is being shown in my code.... i.e. where the error propagation starts
  console.log('Indexed all documents!')
})

module.exports = {
  SampleJoi,
  SampleDb: SampleDb
}
