vite build creates source folder in dist on certain imports

[fjakop]

Describe the bug

I'm creating a vite library relying on @reduxjs/toolkit. When I use "vite build", the output goes to "dist", where a index.js and index.d.ts is placed.
When a certain import from @reduxjs/toolkit is in at least one of the source files, the output folder structure changes and the index.d.ts is placed in dist/src/index.d.ts, which breaks the types declaration in package.json. Also an additional node_modules folder is created in dist, containing a strange file uncheckedindexed.d.ts.

Reproduction

https://github.com/fjakop/vite-build-error

Steps to reproduce

Error case:

• Run npm install
• Run npm run build
• look into dist folder

Success case:

• Remove the import of FetchBaseQueryError from src/index.ts and change the usage to e.g. "string"
• Run npm install
• Run npm run build
• look into dist folder -> the structure is now correct

You need to set the rootDir for typescript plugin:

typescript({ rootDir: 'src' })
