I finally found the solution. You can follow this link https://stackoverflow.com/questions/46599017/error-cannot-determine-the-module-for-class-overlayportal-in-prod/50858210 where you will learn about LOADINCONTROLLER IMPORT.

I verify my code and apply this for all my component who don’t respect the rules.
