ws_analytics[ERROR] [WARNING] IOApp `main` is running on a thread other than the main thread.
ws_analytics[ERROR] This may prevent correct resource cleanup after `main` completes.
ws_analytics[ERROR] This condition could be caused by executing `run` in an interactive sbt session with `fork := false`.
ws_analytics[ERROR] Set `Compile / run / fork := true` in this project to resolve this.

ws_analytics[ERROR] To silence this warning set the system property:
