I've been using this script successfully for the last 9 months or so, but recently (about the last month), I've been receiving the following error, which causes the script to fail to produce any new layers in my ArcGIS online account. I've tried running the script on a couple of Map Services and from a couple different computers with the same result. Any ideas?
