Hopefully the changes @dceejay has made will clear up some of the 'extra' msgs in my tests
Start NR pointing at a new flow
1. open dashboard.
2. open debug in sidebar, then open it in a new window (button bottom right)
3. open a new browser window and open the UI (example [http://localhost:1880/ui](http://localhost:1880/ui))
- ignore warning message in debug
1. add an `inject`, `chart`, and `debug` node
- set `chart` to use the default group and tab
- connect `chart` =\> `debug`
- set `debug` to display complete msg object
2. deploy - debug shows (2) empty msg
3. connect `inject` to `chart` and deploy - debug shows (4) empty msg
4. remove the `inject` to `chart` wire and deploy - debug shows (4) empty msg

That works great, none of my test cases show an empty msg occurring 👍
