Error see webUI for details

Hi all, my Allsky stopped working the other day and I have retrieved it from the roof to check that the camera is all OK and it is. I have tried an identical camera on the Pi with the same result.

I have also checked from command line that the camera is working, using 'rpicam-still -o test.jpg'

I have downloaded the level 3 log file and I have this at the bottom. Can someone possibly give a clue as to what the problem might be.

Thanks in advance...

UPDATE....

I have tried another Pi with the ssd and camera and I get the same problem, which suggests to me that it is a software issue and not the hardware.

The error message implies a problem with software, but I've never seen this before, although I suspect the problem is with rpicam-still.
First thing is to make sure you have the most recent version:

sudo apt-get install rpicam-apps

If that doesn't work, I recommend doing a reinstall of Allsky (stop it, mv allsky allsky-OLD, git clone ... etc) - see the documentation.

If it STILL doesn't work, increase the Debug level to 4, try again, then post the level 4 output.
