I'm thinking now that the problem was with the data point 'MangoES_Disk_Percent_Used'. This fails to import, then all the watch lists, event handlers, etc that are linked to it also fail. It appears this also causes the entire DP hierarchy to fail to load. I believe I'll need to remove all references to this DP from the json file before importing. I understand tha a DP starting 'mangoES' doesn't belong on a GT mango, but there are other points like this (eg MangoES_Disk_Space_Remaining) that seem to be imported OK. Is there something in the import processing that's preventing 'MangoES_Disk_Percent_Used' from being created?
@dcitech those fields are not permissions they are just fields to help categorize users as we plan on building out the user management UI and wanted a few more ways to query users into groups. They currently have no effect on what a user can 'do'.
