Problems connecting to database

[storm lake]

Hi, I am running my nestjs backend with mongodb as a docker-compose:

version: '3.4'

services:
  pfbackend:
    image: backend
    environment:
      NODE_ENV: production
    ports:
      - 3000:3000
    depends_on:
      - mongo_db
  mongo_db:
    image: mongo:latest
    environment:
      MONGO_INITDB_ROOT_USERNAME: test
      MONGO_INITDB_ROOT_PASSWORD: test

If I use this connection string:

    MongooseModule.forRoot('mongodb://@mongo_db:27017/test'),

It connects just fine but can't do anything because it isn't authentified
command find requires authentication
But if I add the authentification in the connection string:

MongooseModule.forRoot('mongodb://test:test@mongo_db:27017/test'),

It gives me the classic Unable to connect to the database
So i'm in quite the pickle and I don't know what to try anymore, anyone know ?

pass the database name test to the dbName configuration option and remove it from the connection uri

MongooseModule.forRoot('mongodb://test:test@mongo_db:27017', {
  // connectionName: '...',
  dbName: 'test', // <--
}),

It seems your solution works, as well as this one from my testing.

'mongodb://test:test@mongo_db:27017/test?authSource=admin'

Thanks a lot for the help

  imports: [
    MongooseModule.forRoot(
      "mongodb://user:password@mongodb:27017/dbname?authSource=admin"
    ),
    RegistrationModule,
    AuthModule,
  ],
  controllers: [AuthApiController],
  providers: [AuthApiService],
})```

Can you create a post in #1025201603843719200 and provide more context about the environment in which your application is being run and the full error message you've encountered? I doubt whether this is 'the same' problem as the original poster.
