What version of python are you running? I see it's the Rocky release, were there any changes made?

I am unable to reproduce the issue on Master i.e. Train. Could you please check that in master. Also could you provide some extra details you might have changed in your cloud environment?

[Eric Xie (eric-xie)]

I use higher version of pep8, and this issue was gone.
So change it to invalid.
