Weird behaviour on Uno

Bug Reports
1 
I would like to report what I think is a bug, on Fuse 1.2.1

After working for several hours, I'm getting this after building (and clearing up my Build folder makes no difference too)

Changed nothing on uno, my .unoproj is almost stock, some .js with nothing regarding uno, removing the code after getting a reply.
Thanks.

Could you please provide a complete reproduction that we could copy-paste and run? There’s a lot of dependencies in the code that aren’t there, so it’s very complicated to clean it up and expect it to still fail.

The root cause might easily be in the JS files you have not shown above, so there’s not much we can do about this report in its current state.

The No implicit cast from 'MainView' to Uno.UX.PropertyObject line hints that you might be doing something wrong related to class names. Exactly what remains to be seen.
