cypress: Component testing with Vite is failing due to the outdated bundled `graceful-fs` version

Current behavior

Component testing with Vite in new projects doesn’t work. There will be errors like:

[vite] Internal server error: Cannot read properties of undefined (reading 'uid') Failed to fetch dynamically imported module: http://localhost:3001/src/components/__tests__/HelloWorld.spec.js?import

The direct cause is the latest version of resolve. It exposes a bug in older versions of graceful-fs. Because Cypress bundles graceful-fs by itself, there seems no way for users to fix it by themselves.

More technical details is explained at https://github.com/browserify/resolve/issues/264#issuecomment-1006948040

Desired behavior

Update the bundled graceful-fs version to >= 4.2.9

Cypress Version

@ljharb the issue has nothing to do with svelte.

In my case it is getting thrown from the Cypress app bundle. Cypress app bundles graceful-fs from where this error is thrown. Here’s the error snippet that shows the source of the error.
