As a quick experiment changed the command’s GetUpcomingList?Count=1 to 0 (zero) and received ‘254’. Tested with 9 and 99 and received those numbers back – 9^th and 99^th upcoming programmes maybe? Probably easier to stick with the expected result and anything else is considered an error.

The Count parameter just tells the GetUpcomingList endpoint how many upcoming
recordings to return. I selected 1 because I assume you really care that at
least one recording will be made in the future.

Count=0 returns ALL upcoming recordings. That's OK, but probably more than
you need.

If "Count" : "0", is returned , there are no upcoming recordings.

If there curl fails, it's unable to communicate with the backend
or at least with the Services API thread.
