This is no issue with pynvim, it merely reports an error that happened within Nvim.

The last line says Error occurred calling omnifunction: csscomplete#CompleteCSS which hints at https://github.com/othree/csscomplete.vim although it doesn't use a variable b:after.

Find out which of your plugins is using such a variable, e.g.

$ grep -iR b:after ~/.config/nvim/plugged
