Screenshots

Additional context
I have tried

   "styleIncludePaths": [
      "../../node_modules/@ng-select/ng-select/themes/default.theme.css"
    ]

And importing it directly in scss file but it does not fix this error

Hi, try adding

"stylePreprocessorOptions": {
   "includePaths": ["node_modules/"]
 }

In the "build" and "build-dev" (if you have it/use it) steps as a default option independent from any configuration, like so:

This will tell to look in the node_modules for that style import or others starting with the @ during build process

In library I do not have stylePreprocessorOptions

I do have option in lib-repo/projects/library/ng-package.json

    "styleIncludePaths": [
      "../../node_modules/@ng-select/ng-select/themes/default.theme.css"
    ]

It does not solve issue

I have created styles.scss with above import and included it in styleIncludePaths it did not work
