### Link to the code that reproduces this issue https://codesandbox.io/p/devbox/gracious-voice-8mxdxl?workspaceId=eb53ed51-e5b9-4293-8298-f0747af5ed78 ### To Reproduce 1. `create-next-app` 2. add `sass-embedded` 3. create a `.scss` file and import 4. `next dev` ### Current vs. Expected behavior ## Current ```console next tried to access sass (a peer dependency) but it isn't provided by its ancestors; this makes the require call ambiguous and unsound. Required package: sass Required by: next@npm:14.2.8 (via C:\<WORKSPACE>\node_modules\next\dist\compiled\sass-loader\) ``` ```console To use Next.js' built-in Sass support, you first need to install `sass`. Run `npm i sass` or `yarn add sass` inside your workspace.
