That was a lingering bug I had fixed in the last update I'd committed. I'd refactored the code at one point, and forgot to rename that function call which is sitting in the event handler in a different code file.
This is where you need to go through the web admin, Advanced -> SQLCVS -> Update and then wait a while. When it says success, you can then reload the router and check the logs. Triggering some lights should generate the status update events, and you'll find your errors will disappear.
If they don't clear up, let me know...
