Service Worker registration failed (text/html)

Bug report

Packages affected

• [x] sandpack-client
• [x] sandpack-react

Description of the problem

console is showing an error since version 2.11.0

Service Worker registration failed: DOMException: Failed to register a ServiceWorker for scope ('https://2-11-2-sandpack.codesandbox.io/') with script ('https://2-11-2-sandpack.codesandbox.io/csb-sw.js'): The script has an unsupported MIME type ('text/html').

Pinning both the client and react pkg to 2.10.0 fixed the issue on our end.

Used here https://github.com/muxinc/media-chrome/pull/791

Repro here, error visible in the console https://media-chrome-docs-a1ftyhecw-mux.vercel.app/docs/en/get-started

I've tried several times and have found a temporary solution for now. You can still use the latest version of @codesandbox/sandpack-react, but you'll need to additionally configure the package.json file, fixing the version of the @codesandbox/sandpack-client package at "2.10.0". I suspect that the issue is caused by the @codesandbox/sandpack-client package as it uses an independent version number and doesn't stay in sync with @codesandbox/sandpack-react, which depends on it. Therefore, the latest version of @codesandbox/sandpack-client directly causes the page to throw an error.
