I don't see a JSON.
Ah sorry. Is this what you're looking for?

This is not a standard Traccar log. If you want some help, please provide full and complete context.
Where do I find the JSON's in the tracker-server.log files?
I’m still having trouble with the speed display. The incoming JSON reports a speed of 31.9 m/s, but the server is showing 36.72 mph. I was actually going about 70 mph at the time. I'm on server version 6.7.3 using the docker image. Any idea whats going on here?
Thanks!
