memberships array on API calls

Hi all,

When i run this:
GET /projects/XXXXXXX/tasks?opt_expand=memberships&opt_fields=memberships

Membersip array returns null.

similarly when i run:
GET /tasks/XXXXXX?opt_expand=memberships&opt_fields=memberships

membership is null, but wen i dont add fields, it comes filled.

Any ideas?

opt_fields and opt_expand are mutually exclusive - you can use or the other, but not both.
