Hi @rajgopalv

I just pushed a fix for that specific problem, it will be released with v 3.0.9

Please consider that $parent.$current.children is not allowed as a target for a query, you have to do something as follows instead:

select from V let $type = (traverse * from (SELECT expand($parent.$parent.$current.children))

Thanks
