I use fastify buildin logger, this logger is awesome, has builtin traceId feature and can access by request.log.info()

https://fastify.dev/docs/v4.28.x/Reference/Logging/

It works.

  const fastifyInstance = fastify({
    logger: true,
  });

  const app = await NestFactory.create<NestFastifyApplication>(
    AppModule,
    new FastifyAdapter(fastifyInstance),
    {
      logger: false,
    },
  );

But this logger log every request and response. I find a solution to close some route. But In Nest I can't find place to config.
