Hi,
It seems like you used a description feature somewhere. However, I don't see any description feature in the basicfamily.ecore metamodel.

If you have made a mistake somewhere, you can still refer to the tutorial solution with File > New > Example... then in Sirius Examples:

Best regards,
Glenn
