Unable to create build after upgrading the app to [email protected]

[shubhdwiv12]

Describe the bug

I have upgraded my project from [email protected] to [email protected]. npm start is working fine but when I am going for the build, I am getting the below error. The build is working fine when I downgraded the application to [email protected]

_Creating an optimized production build...
Failed to compile.

static/css/main.161533bd.css from Css Minimizer plugin
Error: Unexpected '/'. Escaping special characters with \ may help._

Did you try recovering your dependencies?

Yes, I tried recovering my dependencies with [email protected], still, it is causing but working fine with [email protected]

npmPackages:
react: ^17.0.1 => 17.0.2
react-dom: ^17.0.1 => 17.0.2
react-scripts: 5.0.0 => 5.0.0
npmGlobalPackages:
create-react-app: Not Found

Steps to reproduce

(Write your steps here:)

1. There are different third-party dependencies, I have been using along with custom CSS.
2. The Application is working fine and the build is getting created with [email protected]
3. Looks like It is a CSSMinimizerPlugin causing the issue and in the older webpack version, the build is getting created.

Expected behavior

Build should be created.

Actual behavior

Have got the issue of why it is happening after much effort, It is a comment issue (/* */) in the application, if you are facing the same issue, try to check your CSS files and see if you put any wrong comments or check the relative path for the images or background images which you might have given wrong can cause this issue. Hope it helps.

I request the team to add a extra check so that such issues can be taken care of during the npm start
