Could not read source map when debugging test

Describe the bug

Could not read source map for @vite/env: ENOENT: no such file or directory.

Reproduction

Set up a new remix project like so: npx create-remix --template remix-run/indie-stack.
Then add the debugger like described here: https://vitest.dev/guide/debugging.html

When now opening the debugger, the debug console says this:

Could not read source map for file:///Users/user/remix-indie/remix/@vite/env: ENOENT: no such file or directory, open '/Users/user/remix-indie/remix/@vite/env.mjs.map'

Validations

• Follow our Code of Conduct
• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.
• Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.
• The provided reproduction is a minimal reproducible example of the bug.

Reproduce the report with a new Remix project from the remix-run/indie-stack template, Vitest's debugging setup, and the listed Vite and Vitest versions. Start with the debugger output for @vite/env and its missing .mjs.map file; done means opening the debugger no longer reports the ENOENT source-map error.
