Vite tries to read source map from vite-specific path

First raised in vite repo https://github.com/vitejs/vite/issues/4687, but I’m fairly sure it is caused by this plugin.

Describe the bug

While running vite in serve mode (but not build mode), the following error occurs for every component:

Sourcemap for "/redacted/app/src/components/global/AppBtn.vue" points to missing source files
  vite:sourcemap Missing sources:
  vite:sourcemap   /redacted/app/src/components/global/AppBtn.vue?vue&type=style&index=0&scoped=true&lang.sass

Obviously trying to read a file at a path ending with a query is going to fail. Which is what vite seems to be doing. https://github.com/vitejs/vite/blob/8048f900908009757bd20d13ee4af90ce15cd32c/packages/vite/src/node/server/sourcemap.ts#L38-L39

The path without the query is correct though. I assume vite is supposed to intercept the URL and return the source map, but instead seems to use the URL as a path and load from the file system.

Just don’t know why it would do this?

After a little trial and error, I discovered this issue was introduced after version 0.17.11. Downgrading to this version has fixed the issue for me!

Same error here. Downgrading to 0.17.11 fixes the issue.
