Importing from REST JSON doesn't work. Defined procedure returns empty table.

Steps to reproduce:

1. Create connection profile for some REST WS (JSON)
2. Import using this conn profile
3. Create VDB and execute it
4. Call procedure that was defined during import

I have a test scenario for this import here:

I also tried another WS to be sure, that the problem is not in the webservice.
(I tried some iTunes online search)
