Error while building - test_image_with_explicit_dimensions

Hi, I would love to count with your help if possible. I am using “channels” (unstable) and I am almost regreting this. After installing Paperless-NGX I cannot build with `sudo nixos-rebuild switch --upgrade` anymore, because the error below. The only “solution” until now was to rollback to previous generations, but I know that I will need to upgrade at some time. It seems some tests need to be done regarding Python and `fpdf` and the system can’t complete them. Maybe someone could give me ...
