Using SASS_PATH in .env triggers warnings in console

Documentation for using SASS at https://create-react-app.dev/docs/adding-a-sass-stylesheet mentions that I can create .env file with SASS_PATH option so when importing files in SCSS I don’t need to use relative paths and use just for example @import 'vars'.

However, when I use SASS_PATH I get a lot of warning messages in when starting the app with npm run start.

WARNING in ./src/components/Content/Content.module.scss (./node_modules/css-loader/dist/cjs.js??ruleSet[1].rules[1].oneOf[8].use[1]!./node_modules/postcss-loader/dist/cjs.js??ruleSet[1].rules[1].oneOf[8].use[2]!./node_modules/resolve-url-loader/index.js??ruleSet[1].rules[1].oneOf[8].use[3]!./node_modules/sass-loader/dist/cjs.js??ruleSet[1].rules[1].oneOf[8].use[4]!./src/components/Content/Content.module.scss)
Invalid dependencies have been reported by plugins or loaders for this module. All reported dependencies need to be absolute paths.
Invalid dependencies may lead to broken watching and caching.
As best effort we try to convert all invalid values to absolute paths and converting globs into context dependencies, but this is deprecated behavior.
Loaders: Pass absolute paths to this.addDependency (existing files), this.addMissingDependency (not existing files), and this.addContextDependency (directories).
Plugins: Pass absolute paths to fileDependencies (existing files), missingDependencies (not existing files), and contextDependencies (directories).
Globs: They are not supported. Pass absolute path to the directory as context dependencies.
The following invalid values have been reported:
 * "src/styles/_vars.import"
 * "src/styles/_vars.import.css"
 * "src/styles/_vars.import.sass"
 * and more ...

Add SASS_PATH=src to your .env file assuming your SASS files code is in src folder. Add the same variable to any other local environment files you might use like .env.development.

In your .scss files, import using the absolute syntax like @import "src/scss/variables"; instead of @import "scss/variables";
