Error deploying Shopify Hydrogen React framework

I’ve deployed successfully on cloudflare worker the new framework from Shopify: Hydrogen.

Since 10 days it is reporting this error and i don’t know how to solve it. no changes in the worker file and is not working the default boilerplate too, with no changes. that was working some days ago

Error: Something went wrong with the request to Cloudflare…
Uncaught TypeError: Cannot assign to read only property ‘scheduler’ of object ‘#’
at line 11125
[API code: 10021]

the worker is very simple:

import handleEvent from '@shopify/hydrogen/worker';
import entrypoint from './src/entry-server.jsx';
// eslint-disable-next-line node/no-missing-import
import indexHtml from './dist/client/index.html?raw';
import {getAssetFromKV} from '@cloudflare/kv-asset-handler';

async function assetHandler(event, url) {
  const response = await getAssetFromKV(event, {});

  if (response.status < 400) {
    const filename = url.pathname.split('/').pop();

    const maxAge =
      filename.split('.').length > 2
        ? 31536000 // hashed asset, will never be updated
        : 86400; // favico and other public assets

    response.headers.append('cache-control', `public, max-age=${maxAge}`);

  return response;

addEventListener('fetch', (event) => {
  try {
      handleEvent(event, {
        indexTemplate: indexHtml,
        cache: caches.default,
  } catch (error) {
      new Response(error.message || error.toString(), {
        status: 500,

I’m experiencing the same problem. Did you manage to find a solution for this?
