rasa interactive breaks on main

[koaning]

These are the results from running rasa interactive on main on the rasa init project. When introducing a new entity, it seems to break.

Actually duplicate of #9517

Once this is fixed and merged I'll close the other duplicate ticket as well.

This has been fixed and merged to 2.8.x branch. Soon coming to main. Closing this issue manually as it is not closed automatically (because 2.8.x is not the default branch?).
