I can confirm that the search is not working. But the get map data process does work.
I can confirm that there has been a change on the server-side, that prevents the get map data search to receive results. The necessary changes were made for the upcoming CityEngine 2020.1 version. Please excuse the inconvenience.
New version! Can't wait to see what new features it might have. I still have not tried using the array features of the last update but I think that will be a great feature once I put it to use.
