Using a new Community Edition install (v22.214.171.124549 GA) install, specifically for Drill v1.6. When clicking on the Drillbit link in the Navigation pane, a "An error has occurred" popup is displayed, with it link displaying the above error. I encountered this with a previous install with Drill v1.4.
A Drillbit tab is opened, but has no content. The Services window does show 4 Drillbits running, and I can access the Drill web UI with links directly to port 8047.
Should the current Control System be able to manage Drill?
