Is there an existing issue for this?

Current behavior

For some reason, the onApplicationBootstrap hook does not start in the hybrid microservice. It runs in a regular app and in a regular microservice, but not in a hybrid one. Tried with inheritAppConfig: true and false too.

Minimum reproduction code

https://github.com/benefactor1/nestjs-cron-demo

Expected behavior

run onApplicationBootstrap in hybrid MS.

Change this:

const app = await NestFactory.create(HybridModule);

const cronDemoMS = app.connectMicroservice<MicroserviceOptions>(
  {
    transport: Transport.GRPC,
    options: {
      url: `${host}:${port}`,
      package: CRON_DEMO_PACKAGE_NAME,
      protoPath: 'apps/libs/proto/cron-demo.proto',
      loader: loaderConfig,
    },
  },
  { inheritAppConfig: true },
);

await cronDemoMS.listen();

to this:

const app = await NestFactory.create(HybridModule);
app.connectMicroservice<MicroserviceOptions>(
  {
    transport: Transport.GRPC,
    options: {
      url: `${host}:${port}`,
      package: CRON_DEMO_PACKAGE_NAME,
      protoPath: 'apps/libs/proto/cron-demo.proto',
      loader: loaderConfig,
    },
  },
  { inheritAppConfig: true },
);

// new
// vvvvv
await app.startAllMicroservices()

// note "app" here instead of "cronDemoMS"
// vvvvv 
await app.listen();
