I am facing an issue while upgrading my project from angular 8.2.1 to angular 13 version.
After a successful upgrade while preparing a build it is giving me the following error.
Data path "" must NOT have additional properties(extractCss).
I already renamed styleext with style in the angular.json file, but still not able to find the root cause for this error.
angular.json file is as follows.

How to get rid of this additional property?
can anyone help me with this?
thanks in advance!
Just remove the "extractCss": true from your production environment, it will resolve the problem.
The reason about it is extractCss is deprecated, and it's value is true by default. See more here: Extracting CSS into JS with Angular 11 (deprecated extractCss)
