`insert_many` crashes with `violates not-null constraint` when input is an empty Vec and table has null-constraints

[gitmalong]

entities::prelude::Cake::insert_many(Vec::<crate::cake::ActiveModel>::new())
          .exec(&self.db)
          .await
          .unwrap();

Error

Is that maybe desired behavior as there is on_empty_do_nothing ?
