Environment Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 7.1.2

• Cross-platform modules:

• Android Runtime:

• iOS Runtime:

• Plugin(s):

• Node.js: 14.2.0

• [ ] Please, attach your package.json and webpack.config.js as these configurations are usually critical for investigating issues with webpack

It's the standard one. I just generated it. with @nativescript/webpack 4.1.1 I want to add to it by using projectConfigService which needs the injector from CLI
