Cannot run production build

I am developing API with nestjs and TypeORM connected with PostgreSQL. NestJS is using ormconfig.json file to provide database connection.

{
  "type": "postgres",
  "host": "localhost",
  "port": 5432,
  "username": "xyz",
  "password": "xyz",
  "database": "xyz",
  "entities": ["src/**/**.entity{.ts,.js}"],
  "synchronize": true
}

When in dev mode npm run start:dev everything works OK, API is responding, connected properly with database. But when I try run production build: npm run prestart:prod followed by npm run start:prod something breaks and program cannot connect to the database, that cause error:

installation.entity.ts

import { Entity, PrimaryGeneratedColumn, Column } from 'typeorm';

@Entity()
export class InstallationEntity {
  @PrimaryGeneratedColumn()
  id: number;

  @Column({ length: 500 })
  name: string;

  @Column('text')
  description: string;
}

I think that code itself is correct, but there is something wrong with proper configuration.

nestjs ver.6.0.0

try this one: https://github.com/nestjs/nest/issues/184 using a dynamic ormconfig.js (instead of .json)
