Почему в nest.js один экзампляр сервиса используется для многих урлов?

Question

[zzmaster]

Я сделал сервис, используюзий ClickHouse

import { Injectable, OnModuleDestroy } from '@nestjs/common';
import { createClient } from '@clickhouse/client';
import { createId } from "@paralleldrive/cuid2";
import { Request } from 'express';

@Injectable()
export class ClickHouseService implements OnModuleDestroy {
  private readonly clickHouse: any;

  constructor() {
    let id = createId();
    console.log('session=', id)
    this.clickHouse = createClient({
      host: process.env.CLICKHOUSE_HOST ?? 'http://localhost:8123',
      username: process.env.CLICKHOUSE_USER ?? 'default',
      password: process.env.CLICKHOUSE_PASSWORD ?? '',
      session_id: id,      
     });
  }
 
  async query(query: string, settings: any = {}) { 
      settings.wait_end_of_query = 1;
      try {
        const ret = await this.clickHouse.query({
            query: query,
            clickhouse_settings: settings,        
          });
        const response = await ret.json();   
        return response.data;
      } catch (e) {
        console.error(e.message, query);
        return [];
      }
  }

  async onModuleDestroy() {
    await this.clickHouse.close();
    console.log('destroyed')
  }
}


}

В контроллере сервис подключается стандартным способом

@Controller()
export class AppController {
  constructor(
    private readonly appService: AppService,
    private readonly prismaService: PrismaService,
    private readonly clickHouseService: ClickHouseService,
  ) {}

При каждом вызове создается уникальный id сессии.

Тем не менее, на разных урлах (я сделал middleware которое печатает урл) используется одни и та же сессия и она частенько оказывается заблокирована. Почему так и что делать?

@Module({
  imports: [AuthModule, RolesModule, SettingsModule],
  controllers: [AppController, SettingsController],
  providers: [AppService, PrismaService, ClickHouseService, LoggerMiddleware],
})
export class AppModule {
  
  configure(consumer: MiddlewareConsumer) {
