I was excited to give a shot to https://github.com/OpenNeuroDatasets/ds001544/ which has proper publicurl set etc... unfortunately there is something forbidding immediate parallel get (in below example `-J8` but it is the same with `-J2`).  It works on the 2nd try, or if not using -J. Error message states "unknown export location":
