[Pro. user question] Angular 12.2.8 and ng-uikit-pro-standar

I was exhausted to figure out the ng build --configuration production issue over the weekend. It worked with ng serve command but not ng build which made web page responsive didn't work, as (presuming) @angular-devkit/build-angular": "~12.2.8") failed to handle bootstrap css during ng build process.

To reproduce this issue, you can simply to run ng new my-app to generate a very simple Angular 12 app, and then install ng-uikit-pro-standard.git#12.0.0 with npm install command, Once you got ng-uikit-pro-standard.git#12.0.0 installed, follow the official installation doc to load MDBBootstrapModulesPro in app.modules.ts, then you can run ng build --configuration production to build this simple app. Finally, use http-server to start you built app in your dist/ folder, then you can notice the responsive doesn't work.

My workaround for now is to downgrade Angular to 11.2.14 and downgrade ng-uikit-pro-standard.git to 11.1.0 and using "@angular-devkit/build-angular": "0.1102.14" for building.

Below is my package.json file.
