The 1.17 update has apparently introduced a bug in the Query Widget. The Current Map Extent and 0ft Buffer (or other units of measurement) options appear to be broken. Using these options will result in zero query results and the console logging a 400 error. Other Spatial Queries, Drawn Graphic with a non-zero Buffer Distance and Selected Features from Data Source, appear to work properly. I have found this issue in Developer Edition 1.17 and ArcGIS Online.
Here is a demo app.
