Transforms cannot group by boolean

When I try to add a boolean field into the group_by list of a transform, preview returns me an error:
"type" : "illegal_argument_exception",
"reason" : "Value of type [class java.lang.Boolean] is not supported"

Am I using it the wrong way?

Thanks for reporting, I created an issue in the github repository.
