MongoParseError: Invalid message size: 1347703880, max allowed: 67108864 (NestJS & MongoDB Docker Container)

Question

I am working on a NestJS Project that is based on micro-service architecture (Kafka, CQRS Patter).

I have created a shared mongodb database inside docker container and exposed the port to 8081 Port which is accessible via browser(I am using mongo-express ui). Here is the docker-compose.yml file

version: '3.1'

services:
mongo:
    image: mongo
    restart: always
    environment:
        MONGO_INITDB_ROOT_USERNAME: root
        MONGO_INITDB_ROOT_PASSWORD: PWD

mongo-express:
    image: mongo-express
    restart: always
    ports:
        - 8081:8081
    volumes:
        - data-volume:/data/db
    environment:
        ME_CONFIG_MONGODB_ADMINUSERNAME: root
        ME_CONFIG_MONGODB_ADMINPASSWORD: PWD
volumes:
    data-volume:

And in my NESTJS Service, I have defined mongo connection like this: (app.module.ts)

import { Module } from '@nestjs/common';
import { APP_FILTER } from '@nestjs/core';
import { CqrsModule } from '@nestjs/cqrs';
import { MongooseModule } from '@nestjs/mongoose';
import { UserModule } from './user/user.module';

@Module({
  imports: [UserModule, MongooseModule.forRoot('mongodb://localhost:8081/urooj', {
     useNewUrlParser: true,
     useFindAndModify: false,
     useCreateIndex: true
 })],
 controllers: []
})
export class AppModule {}

And in my user module I am defining User schema: (user.module.ts)

import { Module } from '@nestjs/common';
import { CqrsModule } from '@nestjs/cqrs';
import { UserController } from './user.controller';
import { UserHandler  } from "./command/handler/index";
import { MongooseModule } from '@nestjs/mongoose';
import { UserSchema } from './models/user.model';
import { UsersRepository } from './user.repository';
import { UserService } from './user.service';

@Module({
    imports: [
       CqrsModule,
       MongooseModule.forFeature([{name: 'User', schema: UserSchema}])
    ],
    controllers: [UserController],
    providers: [
       ...UserHandler,
       UserService
    ]
 })
 export class UserModule {}

But I am getting this error which I tried finding the solution but i am bit unlucky in solving this issue from quite sometime now.

events.js:292
  throw er; // Unhandled 'error' event
  ^

Thank you for the help in advance.

Answer 1

I fixed this above issue by Exposing Port to mongo service in my docker-compose.yml apart from mongo-express service.

But I ran into another issue now and that is related to authentication when connecting to mongodb using nestjs. Though Mongodb Container can be accessed using compass. I will be debugging this and if required will raise a new question in SO.
