400 (Bad Request) when creating a simple display with a multi-state symbol

since we started getting 400 (Bad Request) messages on some of our displays after upgrading to PI Vision 2017, I started to investigate why these messages showed up since they did not show up in PI Coresight 2016.


I created a simple display with only one ellips symbol and configured it to be a multi-state symbol by attaching an attribute from AF. Once I attached the attribute, PI Vision starts to throw out the messages seen on the right in the screen shot below every 5 seconds.


Any idea why?
