This error also happened last night:

I tried to restart the ./process.py -c configuration.ini -d /export/obs/20260613_0/204653/ -m 480 and would give the following output/error.

Now it also occurred with the command ./process.py -c configuration.ini -d /export/obs/20260613_0/204653/ -C 2 -r

Looking at the obs directory, there is a file test.fits, when I rmeove the file I can restart process.py

I have also added the last two files that where being processed when the error happened.
