Description of the problem

I am embedding Codesandboxes in my React (vite) app. Everything seems to work fine, however i noticed that when i load the Codesandbox in the embed (this doesnt happen when i open the editor on Codedsandbox.io) - i see this JS Error inthe console:

browserfs.rollup.js:11171 Uncaught TypeError: Cannot read properties of null (reading 'isReadOnly')
    at browserfs.rollup.js:11171:1
    at Worker.<anonymous> (browserfs.rollup.js:11168:1)
(anonymous) @ browserfs.rollup.js:11171
(anonymous) @ browserfs.rollup.js:11168

I've also noticed, which i assume is somehow related subsequent errors:

codesandbox.io/public/14/vs/editor/editor.main.js:146 Uncaught Error: Cannot read properties of undefined (reading 'readFile')

I appears browserfs is being loaded from https://codesandbox.io/static/browserfs12/browserfs.min.js.

Any idea why this is happening?

The codesandbox.io embed seems to work fine - but the browser console has many errors generated from Codesandbox.io embed.

How has this issue affected you? What are you trying to accomplish?

To Reproduce

Link to sandbox: link (optional)

Your Environment

Start by reproducing the embedded CodeSandbox in a React/Vite app using Chrome, then inspect the browserfs.rollup.js error and the related TypeScript worker readFile failure. Compare the embed with the editor on codesandbox.io and trace when browserfs is loaded; done means identifying the cause and confirming the embed no longer emits these errors.
