Describe the bug
When running browser tests using Vitest's browser testing guide, I get the following warning:
Sourcemap for "/@react-refresh" points to missing source files
I set up a new project and am seeing this warning right from the start, before adding any custom code. Let me know if there's any additional info or reproduction steps you'd like.
Tests are running fine, it just shows this warning.
Not seeing this warning when using @vitejs/plugin-react.
Reproduction
https://github.com/wuifdesign/react-swc-bug
Steps to reproduce
check out the repo and run npm run test:browser
Also added @vitejs/plugin-react to the repo to see the warning is gone after switching to this package.
