After updating to the November 2017 build this morning, I am no longer able to select Power BI Service data sources in Power BI Desktop. The error in the screenshot below pops up immediately every time. I tried uninstalling and re-installing, rebooting, etc. I haven't found a way to clear the error. I'm dead in the water until I can get this fixed. I used a sniffer to get the json coming back from the service, and there are two instances of the same workspace/group in the file. It looks like the service is returning bad data. HELP!!!
