I want to be able to query the number of item requests during a certain time period. If I use:
ap_hits = ap_item.usage(date_range = '6M, as_df = True)

But if I uses date_range = '24', '7D', '30D', or '60D' it comes up as None

As you can see from the '6M' option, I do have requests in the last 7D. Why can't I do get the requests with specific time dates less than 6 months?
