There is a reason, you can’t compile an app if the sockets are empty. Click the error icon and it’ll show the error reason.

I think this is a bug with performance mode, does it happen if you disable it?


No only when performance mode is on and i have re-edit the report.

I can confirm this issue, same happens to me.


It used to show a warning, now it shows an error.

App Inventor does the same. Property blocks must be filled anymore, because (as far I know) setting the property to null for non-nullable properties causes an error (runtime or/and during compile), so it is better to show a red error icon instead of warning. However, methods can still have empty sockets.
