Error generating production build

[eliseurm]

This version has been updated for Angular12 and is not being built for production.

ng build --output-path = dist --configuration production

Error:

✖ Index html generation failed.
undefined: 5: 144452: property missing ':'

There seems to be a problem with the way scss is going to be used going forward.

DevExtreme must configure its styles to meet this demand, in other projects I have the same problem.

Hi @eliseurm,

This issue is related to the regression in the Angular library. Please check this GitHub issue for more information: angular/angular-cli#20760
According to Alan's comment, the issue is caused by Angular-CLI. The Angular-CLI team will fix it in the scope of the following GitHub issue: reworkcss/css#154.

In the meantime, you can use the inlineCritical option to resolve the issue:

"optimization": {
                "scripts": true,
                "styles": {
                  "minify": true,
                  "inlineCritical": false
                },
                "fonts": {
                  "inline": true
                }
              },
