title: Object gotten from the NestFactory has all the internal dependencies as undefined - NestJS
body: <p>I get an object from NestFactory and then I call a function. There is another class injected inside service class. All the dependencies inside the service are not accessible.</p>
  <pre><code>const FASTIFY = new FastifyAdapter();
  const app = await NestFactory.create&lt;NestFastifyApplication&gt;(AppModule, FASTIFY, {
          bufferLogs: true, // do wait till LoggerService is available
  });
  const service = app.get&lt;ServiceClass&gt;(ServiceClass);  // service object is obtained from container
  console.log(service.anotherRepository); // repository and injected objects are undefined.
  </code></pre>
  <p>Service object is obtained from container and then I can see the code goes into service class but all the dependencies defined inside the service class are undefined.</p>
  <p>I have set the scope of all of them to DEFAULT.</p>
  <pre><code>@Injectable({ scope: Scope.DEFAULT })
  </code></pre>
