Почему контекст не видит зависимость?

Question

[Вика Мармеладка]

Вот мой модуль БД с конфигом в useFactory:

/**
 * Токен сервиса БД
 */
export const DATABASE_TOKEN = 'PG_CONNECTION';

@Global()
@Module({
  imports: [ConfigModule],
  providers: [
    {
      provide: DATABASE_TOKEN,
      inject: [ConfigService],
      useFactory: (config: ConfigService) => {
        return new Pool({
          host: config.get<string>('DB_HOST'),
          port: config.get<number>('DB_PORT'),
          user: config.get<string>('DB_USER'),
          password: config.get<string>('DB_PASSWORD'),
          database: config.get<string>('DB_NAME'),
        });
      },
    },
    UsersRepository,
  ],
  exports: [UsersRepository, DATABASE_TOKEN],
})
export class DatabaseModule {}

App модуль куда импортирую БД модуль (так он он глобальный, то не важно куда его импортировать)

@Module({
  imports: [
    ConfigModule.forRoot({
      isGlobal: true,
    }),
    DatabaseModule,
    TelegramModule,
    WinstonModule,
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

Здесь мой репозиторий.

@Injectable()
export class UsersRepository {
  constructor(@Inject(DATABASE_TOKEN) private readonly db: Pool) {}

  public async createUser(telegramId: number): Promise<void> {
    await this.db.query('INSERT INTO users (telegram_id) VALUES ($1)', [
      telegramId,
    ]);
  }
  public async getUserByTelegramId(telegramId: number) {}
  public async getUserById(id: number) {}
}

UndefinedDependencyException [Error]: Nest can't resolve dependencies of the UsersRepository (?). Please make sure that the argument dependency at index [0] is available in the DatabaseModule context.

Potential solutions:
- Is DatabaseModule a valid NestJS module?
- If dependency is a provider, is it part of the current DatabaseModule?
- If dependency is exported from a separate @Module, is that module imported within DatabaseModule?
  @Module({
    imports: [ /* the Module containing dependency */ ]
  })

Waiting for the debugger to disconnect...

Ошибка возникает, когда я инжечку @Inject(DATABASE_TOKEN) private readonly db: Pool. Но я не понимаю почему. Помогите пожалуйста
