Can't get Inertia SSR to work, using React and Laravel 10 stack.

I am struggling with implementing Inertia's SSR into my application. I tested on new Laravel applications and I'm getting same results - content is not rendering on server side. I checked by disabling JavaScript and it definitely isn't working.

Here is my ssr.jsx code:

import React from 'react';
import ReactDOMServer from 'react-dom/server';
import { createInertiaApp } from '@inertiajs/react';
import createServer from '@inertiajs/react/server';
import { resolvePageComponent } from 'laravel-vite-plugin/inertia-helpers';
import { route } from '../../vendor/tightenco/ziggy';

const appName = import.meta.env.VITE_APP_NAME || 'Laravel';

createServer((page) =>
    createInertiaApp({
        page,
        render: ReactDOMServer.renderToString,
        title: (title) => `${title} - ${appName}`,
        resolve: (name) => resolvePageComponent(`./Pages/${name}.jsx`, import.meta.glob('./Pages/**/*.jsx')),
        setup: ({ App, props }) => {
            global.route = (name, params, absolute) =>
                route(name, params, absolute, {
                    ...page.props.ziggy,
                    location: new URL(page.props.ziggy.url),
                });

            return <App {...props} />;
        },
    })
);

console.log('starting server')

here is my app.jsx code:

`import '../css/app.css';

import React from 'react';
import { hydrateRoot, createRoot } from 'react-dom/client';
import { createInertiaApp } from '@inertiajs/react';
import { resolvePageComponent } from 'laravel-vite-plugin/inertia-helpers';

const appName = import.meta.env.VITE_APP_NAME || 'Laravel';

createInertiaApp({
    title: (title) => `${title} - ${appName}`,
    resolve: (name) => resolvePageComponent(`./Pages/${name}.jsx`, import.meta.glob('./Pages/**/*.jsx')),
    setup({ el, App, props }) {
      createRoot(el).render(<App {...props} />);
    },
    progress: {
        color: '#e05847',
    },
});
console.log('starting client')`

vite.config.js:

import { defineConfig } from 'vite';
import laravel from 'laravel-vite-plugin';
import react from '@vitejs/plugin-react';

export default defineConfig({
    plugins: [
        laravel({
            input: 'resources/js/app.jsx',
            ssr: 'resources/js/ssr.jsx',
            refresh: true,
        }),
        react(),
    ],
});

I am not seeing any changes that would indicate SSR is running, no error messages, no change of the code, nothing.

Does anyone have any suggestions?
