When developing widgets for the Operations Dashboard in Javascript the function getassociatedselectiondatasourceproxy always appears to fail. My dataSource supports selection, it attempts to fire the query but an error occurs (screenshot attached). I have tried this with a number of data sources including esri ones and they are hosted by server 10.3
I can't work out how you log a bug with esri. My local distributor directed me towards the $2000 EDN support add on, but I'm not really up for paying to log a potential bug.
