How do you debug AOT white page?

Hi guys,
I’m trying to upgrade my old Ionic to the latest versions of Ionic and Angular. The app works in debug mode. But when switching to production build (enabling AOT with --aot), the app stays white with no errors in console.

I already faced this kind of issue a lot when upgrading Angular/Ionic and it’s really frustrating. I cannot be the only one !
What technique do you use to debug that kind of situation ? How do you identify the issue ?

Thanks a lot !
