command.ts message has no ok so i patched the file locally "ok" in message && !message.ok

    handleResponse(response: Uint8Array): void {
        if (!this.current) throw new Error('Got handleResponse without active command');
        const deserializer: BSONDeserializer<BaseResponse> = this.current.responseType ? getBSONDeserializer(mongoBinarySerializer, this.current.responseType) : deserializeBSONWithoutOptimiser;

        try {
            const message = deserializer(response);
            const error = handleErrorResponse(message);
            if (error) {
                this.current.reject(error);
                return;
            }

            if ("ok" in message && !message.ok) {
                this.current.reject(new MongoError(message.errmsg || 'error', message.code));
            } else {
                this.current.resolve(message);
            }
        } catch (error: any) {
            if (error instanceof ValidationError || error instanceof SerializationError) {
                if (this.current.responseType) {
                    const raw = deserializeBSONWithoutOptimiser(response);
                    console.log('mongo raw response', inspect(raw, {depth: null}));
                    if (raw.errmsg && raw.ok === 0) {
                        const error = handleErrorResponse(raw);
                        if (error) {
                            this.current.reject(error);
                            return;
                        }
                    }

                    this.current.reject(new MongoError(`Could not deserialize type ${stringifyType(this.current.responseType)}: ${error}`));
                    return;
                }
            }
            this.current.reject(error);
        }
    }

PS: the following is broken because of webpack #351

PrimaryKey is still not working

This make everything "works" if i assign a `MongoId`to the entity.

Problem 2) Maybe i discover another bug with the PrimaryKey? if i change id to _id everything works as expected.

export class BaseEntity {
  id: MongoId & PrimaryKey = "507f1f77bcf86cd799439011";
  created: Date = new Date;
  updated: Date = new Date;

  static from(data:any){
    const entity = new this();
    for(const k in data){
      entity[k] = data[k];
    }
    return entity;
  }
}

PrimaryKey is ignored?

It seems so, if i change the definition to

export class BaseEntity {
  id: MongoId & PrimaryKey; // no initializer
  created: Date = new Date;
  updated: Date = new Date;

  static from(data:any){
    const entity = new this();
    for(const k in data){
      entity[k] = data[k];
    }
    return entity;
  }
}

and run a query

@CristianPi thanks, that was the missing piece. Fixed in https://github.com/deepkit/deepkit-framework/commit/c1d6c415199804d966ce17ceb235a050de011da3

I see, but you have to try with authentication:

version: '3.1'

services:

  mongo:
    image: mongo:5.0.10
    restart: always
    ports:
      - 27017:27017
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: root
      MONGO_INITDB_DATABASE: root-db
    volumes:
      - ./tmp:/data/db
      - ./tmp:/data/configdb
      - ./mongo-init.js:/docker-entrypoint-initdb.d/mongo-init.js:ro

mongo-init.js

print('START #################################################################');

var list = ["db"];

for(var i = 0; i < list.length; i++) {
  var name = list[i];
  db = db.getSiblingDB(name);
  db.createUser(
    {
      user: 'user',
      pwd: 'password',
      roles: [{ role: 'readWrite', db: name }],
    },
  );
}

print('END #################################################################');

then in your code

const database = new Database(new MongoDatabaseAdapter(`mongodb://user:password@localhost:27017/db`), [User]);

ps: i think you can create an user without using the mongo-init.js initializer, just try connecting with username & password
