Basic react server side rendering does not work on Deno Deploy but does locally

The below application work correctly locally but fails on Deno Deploy. On Deno Deploy, all my responses have a status 500 and logs show an error ReferenceError: h is not defined at handler (file:///src/server.tsx:8:33).

import React from "https://esm.sh/react@18.2.0";

// @deno-types="https://denopkg.com/soremwar/deno_types/react-dom/v16.13.1/server.d.ts"
import ReactDOMServer from "https://esm.sh/react-dom@18.2.0/server";


const handler = (request: Request): Response => {
    const body = ReactDOMServer.renderToStaticMarkup(
        <div >hello world</div>
    );
    return new Response(body, {status: 200});
};

Deno.serve(handler);

    return new Response(body, {status: 200});
};

Deno.serve(handler);

I am sure that I am doing something stupid but I cannot figure out what. Can you help me spot it. cheers, didier

What a method prefixed with `#` means?

This is perhaps the stupidest question ever. But I often see method with names prefixed with a # character in typescript. What does it mean? Google does not seems to know either. example: https://deno.land/std@0.187.0/streams/text_line_stream.ts?source#L40

In memory Deno Kv

Hi there, I am exploring with Deno Kv and it looks great! But my test are failing because I reuse the same database over and over. Is there a way to initialize an in memory version of Deno.Kv ? Something like sqlite in memory (https://www.sqlite.org/inmemorydb.html)?
