Production Mode CSS problem

Hi, I’m using Vaadin 14.4.4 with Gradle 6.3 and Spring Boot.

When I was creating a website in developer’s mode everything was working well. Now I switched to productionMode = true and website doesn’t load a single css file.

I’m trying to use one css file per class.

After switching back to developer’s mode the CSS formatting is not working as it used to.

I tried vaadinClean, vaadinBuildFrontend and vaadinPrepareFrontend but that doesn’t seem to fix my problem…

Do you guys have any suggestions does any of you interfered with the same problem as I ?
