Just letting you know that the issue has been fixed. I tried your project again and it now re-compiles successfully and when reloading the preview it reflects the changes. I am going to close this issue but if there's still an issue you're running into, feel free to file a new ticket.

Wow, that was a quick fix. You deserved a subscription for that 👍 .

@jrvidal @d3lm Thank you very much, I can confirm that it also works in newly set up projects.
