Till Westmann commented on ASTERIXDB-1401:
------------------------------------------
Adding some dataverse before your example
{code}
drop dataverse test if exists;
create dataverse test;
use dataverse test;
create type typeX if not exists as open {
id : int64
}
drop type typeX if exists
{code}
this works for me on the current master
(22302e75d02f0dbd4ca8ec21e40146a764692b4a).
