Is there any error happening?
No contradiction. Sinks are always syncs (haha), so noutput_items == the number of input items (by definition). The actual output buffer, however, is empty -- so we can't use the length of the output buffer to tell the scheduler how much we consumed. In a sync block, there is no argument "ninput_items", so we can't use that, either.
