Pluggable Widget works in Mendix 9 but not in Mendix 8

We have created a pluggable widget that uses @mendix/pluggable-widgets-tools": "^9.18.0. The widget works correctly after it was imported into a Mendix 9 project. When we try to use the same widget in a Mendix 8 project we are seeing in the UI that the widget is Unknown. I dont see any console errors.    Are we able to create widgets with the current widget generator or do we need to recreate the widget with an older generator?

Hi Jason, 

Have you fixed this? We have the same problem…

Kind regards,
