Describe the bug

When running vitest I get these warnings. Unable to seem to solve/remove them from showing up.

Sourcemap for "/Users/user/code/vite-repo/node_modules/vitest/dist/runners.js" points to missing source files
Sourcemap for "/Users/user/code/vite-repo/node_modules/@vitest/snapshot/dist/index.js" points to missing source files
Sourcemap for "/Users/user/code/vite-repo/node_modules/vitest/dist/chunks/setup-common.AQcDs321.js" points to missing source files
Sourcemap for "/Users/user/code/vite-repo/node_modules/.vite/deps/chunk-S2L5SCOP.js" points to missing source files

My test output from my codebase:

npx vitest run --browser.headless

Any updates for this? I want to hide those warnings.

@jamesg1 or anyone else, can you minimize the reproduction so it's easier to see what's causing this?

Its within that repo I posted above.

Do you mean you pushed changes that reduces the reproduction? I don't see any recent changes in https://github.com/jamesg1/example-vitest/commits/main/.

The first thing any maintainer who wants to start fixing this issue is to minimize the reproduction into a subset of files that are needed to cause this. For example, are all of the 66 dependencies and 28 devDepdencies required for the bug? Does it still happen if you remove the setupTests.ts?
