NestJS onModuleInit not working when specific service is added to constructor

I have a bunch of services defined in my NestJS project. Some of the services are used as common services in a lot of other services. So they are imported in a few modules as well. But I noticed that when specific service srvD is imported in another service srvE2, the onModuleInit is not being called when the project starts.

The project starts without any error. Not really sure what's happening.

An example of the project structure. Issue is in srvE2

srvA.ts

@Injectable()
export class SrvA {
  constructor(
    private somePkgSrv: SomePkgSrv,
  ) {}
}

srvB.ts

@Injectable()
export class SrvB {
  constructor(
    private srvA: SrvA,
  ) {}
}

srvC.ts

@Injectable()
export class SrvC {
  constructor(
    private srvA: SrvA,
    private srvB: SrvB,
  ) {}
}

srvD.ts

@Injectable()
export class SrvD {
  constructor(
    private srvA: SrvA,
    private srvB: SrvB,
    private srvC: SrvC,
  ) {}
}

srvD.module.ts

@Module({
  providers: [SrvA, SrvB, SrvC, SrvD],
  exports: [SrvD],
})

srvE1.ts

export class SrvE1 implements OnModuleInit {
  constructor(
    private srvA: SrvA,
    private srvB: SrvB,
    private srvC: SrvC,
  ) {}

  async onModuleInit() {
    console.log ('I can print! Yay!')
  }
}

srvE2.ts

export class SrvE2 implements OnModuleInit {
  constructor(
    private srvA: SrvA,
    private srvB: SrvB,
    private srvC: SrvC,
    private srvD: SrvD,
  ) {}

  async onModuleInit() {
    console.log ('I refuse to print so long as SrvD is here. Comment it and I will             
    print')
  }
}

srvE.module.ts

@Module({
  import: [SrvD], // the module
  providers: [SrvE1, SrvE2], // the services
  exports: [SrvE1, SrvE2],
})
