#feathersjs/socketio-client connection timeout. Why? - feathersjs

Question

I maked follow:
feathers g app # with socket and rest
feathers g service # todos & NeDB
npm start
and simple client for this. I copy code from documentation
https://docs.feathersjs.com/api/client/socketio.
const feathers = require('#feathersjs/feathers');
const socketio = require('#feathersjs/socketio-client');
const io = require('socket.io-client');
const socket = io('http://localhost:3030');
const app = feathers();
app.configure(socketio(socket));
app.service('todos')
.on('created', message => console.log('New message created', message));
app.service('todos').find().then(r => {
console.log(r)
}).catch(e => console.log('error',e))
app.service('todos').create({
title: 'A message from a REST client'
});
this client code get me timeout errors for find() and create() methods
But if I make POST request by CURL, I have onCreated message in console
Why I got errors on create() and find() calls?
UPDATE:
I maked git repo for easy reproduce this problem
https://github.com/tolyanor/feathersjs-error
UPDATE2:
I change autogenerated file src/app.js like in feathers example chat application https://github.com/feathersjs/feathers-chat/blob/master/src/app.js
Now I CAN call service method create on client, but CAN NOT receive onCreated message. So, this code
app.service('/todos')
.on('created', message => console.log('New todos created', message));
never calling

You are using a Feathers v3 client with a Feathers v2 server. Old clients will be backwards compatible with new servers but not the other way around. Follow the migration guide to upgrade your server or generate a new application using #feathersjs/cli (feathers --version on the command line should show v3.5.0 or later).
