Issue with docs

You have:

app.connectMicroservice({
  strategy: new JsonRpcServer({
    path: "/rpc/v1",
    port: 8080
    server: app.getHttpAdapter()
  })
});

should be:

app.connectMicroservice({
    strategy: new JsonRpcServer({
        path: '/rpc/v1',
        port: 3200,
    }),
    server: app.getHttpServer(),
});
