Hello all,
unfortunately I have a small problem and can not cope with the error analysis 
I can not restart since today, it always gives me the error “argument of type ‘NoneType’ is not iterable”.
is thrown out.
Attached is an excerpt from the log, maybe you can figure it out.
BTW: Does anyone know how I can check the lines specified in the error message? or where they are?
Thanks a lot!
