"Create a new Stateless form from an existing form" feature problem


The new feature Create a new Stateless form from an existing form  -  throws an error "Stateless forms can not have unique fields..." when it's used for the fields which have Unique property. Probably this is a situation not taken into consideration when this feature was built.

Also, the error with the reference line doesn't make sense for the developer, because the code is not editable in there.
