How can I check as a validator in workflow transition, that a Cascading List field is not empty?

Dear everyone,
I want to make sure that my cascading list field "Agile Release Train/Team" is not empty during a workflow transition.

When I add the validator "Fields Required (JSU)", Jira only checks the first level (parent) of the field, allowing the children keep being empty.

Therefore, I want to test whether a Regular Expression Check (JSU) works. What value do I need to enter into the field "Regular expression" to check that the user gets an error if the parent has a valid value, however, child = none?

Have you check the children issues is applied the same workflow like the parent issue ?
