vylc opened a new issue #4347: [Druid] Explore view throws error when group by is applied
URL: https://github.com/apache/incubator-superset/issues/4347
 
 
   Chart: Line/Time series
   Datasource: Druid
   
   Unsure what is going on--cryptic error is thrown when I try visualizing the dataset as a line chart with a group by on a single dimension. Works fine on the non-Druid datasource
