getting vague "error" from PymodeLint?

hi, I've been using the Pymode plugin for vim for a while (basically just for the PymodeLint function, it's very helpful to me) but I recently installed it on a new computer and after running PymodeLint I'm getting these errors for this code:

am I missing something? what is the problem with the code?

I'm using Vim 9.0 on macOS 12.6.7.

Thank you!
