Hi Rohit -
I think I was incorrect about it needing to be my org URL. I think it might have something to do with the order I run the cells. Sometimes I need to re-run the log in cell before I can execute an analysis.
Are you creating more than one GIS object? The last created GIS object is used for analysis by default, unless you explicitly pass in a gis parameter to specify the GIS (or create the GIS object with set_active=False)
I can confirm that this issue is being resolved as well in the next update. Since you're Esri staff, you can get access to the latest code from the internal respository.
