Wix Members: New wix-members & wix-members-backend APIs

I’m seem to run into a little bit of trouble with the new members. getMember functions in the backend. I can’t return the ‘FULL’ fieldsets when I call these functions from a backend event such as wixPaidPlans_onPlanPurchased . I can only get the public info and not the full info, for example to get a client’s e-mail address.
