Happened to me once, 6 days ago.
I have driven 5k miles since AP, and this never happened. But last Saturday, after driving 16mi with AP, parking my still clean car/windshield for 10 min with camera and front radar facing away from sun, I started up and saw this message for the first time. Rebooting didn't help, so called Service. They said, known software bug, working on a fix. Can be caused by dirty windshield in front of camera or front radar, but often not, like in my case. So he said once it sits for awhile - 60 to 90min - try restarting, and almost always goes away. It did, hasn't returned yet. My guess is that, like other posters mentioned, the CAN bus delays a sensor read outside of its tolerance at startup, and it throws an error. My guess is the software fix is to increase the time for startup sensor detection a few hundred milliseconds before throwing the error.
I've had this too... it's very common.
Steps: reboot (as indicated in this thread). Wash the window in the camera area. Also check the front radar to see if it's obstructed (ice collects there commonly, but mud can be a problem as well). If this doesn't work, ask Tesla to look at logs. Some owners have reported camera failure and have to go have it replaced.
