nestjs REQUEST scoped service provider

Question

i'm trying to use my custom logger service inside other services, but i have noticed that when i'm provide logger service to other service didn't call any lifecycle hooks anymore

there is code of my logger service

@Injectable({ scope: Scope.REQUEST })
export class LoggerService {
    constructor(
        @Inject(REQUEST) private readonly payload: RequestContextHost<RequestPayloadWithCorrelationId, TcpContext>
    ) {}
  .... // other methods
}

I need this class for get unique request id and log it, but i use this service in another which implements OnModuleInit method, so when i provide logger to this service, it just don't call onModuleInit method

Maybe getting request id for logger is wrong?

Lifecycle hooks are not called for request scoped dependencies as per the docs

The lifecycle hooks listed above are not triggered for request-scoped classes. Request-scoped classes are not tied to the application lifecycle and their lifespan is unpredictable. They are exclusively created for each request and automatically garbage-collected after the response is sent.

It seems like you'll need another method around using a request scoped logger, at least for this class.
