I am getting ERROR in Expected a pseudo-class or pseudo-element. error after running ng build with "optimization": true parameter. (If I disabled the optimization flag the build will pass but resulted with like 20mb large vendor.js file!)
I had searched online that the error indicated some css format issue. However, even I pass the --verbose flag, angular won't give me the proper information about which css file angular failed to parse. What can I do to make angular give me more relevant information? For this project, there are over a thousand searched results for :, it's not so practical to debug manually. Also this is an angular 9 project.
