TypeOrmModule causes controller params to be undefined about nest

TLDR; make sure you use the latest version (so the reflect-metadata version is in sync)

Please, provide a minimum reproduction repository.

You can also try removing the lock file & node_modules folder and re-running npm install

So I have tried to provide a reproduction on Stackblitz, the problem is that it can't connect to DB so it throws an error an won't run. I can add once again my very basic app.controller and app.module.
regarding the deletion of node modules and re-run npm i - I have already done it and it didn't solve.
Thanks for your efforts !

my app.controller:

@Controller('app')
export class AppController {
  constructor(private readonly appService: AppService) {}

  @Get('/:id')
  getHello(@Param('id') id: string): string {
    console.log(id);
    return this.appService.getHello();
  }
}

my app.module:

@Module({
  imports: [
    UsersModule,
    ScheduleModule.forRoot(),
    CacheModule.register({ isGlobal: true }),
    HttpModule,
    ConfigModule.forRoot({
      isGlobal: true,
      envFilePath: ['.env.dev'],
    }),
    TypeOrmModule.forRootAsync({
      imports: [ConfigModule],
      inject: [ConfigService],
      useFactory: async (configService: ConfigService) => ({
        type: 'postgres',
        autoLoadEntities: true,
        synchronize: true,
        host: configService.get('DB_HOST'),
        port: configService.get('DB_PORT'),
        username: configService.get('DB_USERNAME'),
        password: configService.get('DB_PASSWORD'),
        database: configService.get('DB_DATABASE'),
      }),
    }),
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

For me @kamilmysliwiec's suggestion worked.

@moshicohen I updated my project to use all the dependencies you listed and my controller's still worked. Maybe inspect your package-lock.json and ensure the correct reflect-metadata version is being used and something else isn't pulling in 0.1.12.

You are right guys, it was finally the version pf reflect-metadata.
When I ran: npx npm-check-updates -u it didn't update it.
I had to manually: npm install reflect-metadata@^0.2 and it solved it.
Thanks !
