Description

A clear and concise description of the problem...

I have created a new project using the cli by selecting the styles type as SASS but the generated files are SCSS but still the configuration in angular.json is points to SASS file and it returns error while serving.
These are config contains related to SASS

 "styles": [
              "src/styles.sass"
           ],

 "karmaConfig": "src/karma.conf.js",
            "styles": [
              "src/styles.sass"
            ],

 "schematics": {
        "@schematics/angular:component": {
          "style": "sass"
        }
      },
