Actually, it works. I figured what the problem was. The problem was with my Russian government blocking the Elm. Parcel wanted to download some packages. I turned on vpn and it worked.
I knew there was something strange about it. Because the code didn't have a mistake. And when I for example purposefully introduce a mistake the parcel/elm would show it to me in the browser.
It's great you figured that out!
