TypeError: cannot unpack non-iterable NoneType object

Hi,
I was trying to perform comparM aai_wf on two genomes of bacteria . I used the command
aai_wf mygenomes out --proteins
The error I received was -

How do I solve it?

Perhaps this is an issue with the sort command. What flavour of Linux are you using? See the note at the top of the CompareM README file:
