Owntracks.py error in logs: Unable to Parse Payload as JSON:Hello

I am hoping someone can tell me why I get this error in the system info log? It happens each time I restart Hass.io. I’ve searched all my files for the text “Hello” and come up empty.

If you use Mosquitto MQTT broker, try deleting and reinstalling the broker. It worked for me…
