This is in neovim 0.11. Perhaps somewhat relevant, I am using blink.cmp and fzf-lua. This does not preclude me from using Diffview, just gets an annoying popup.
Kindly, let me know what else you need to know.
Overall this i
Expected behavior
I did not expect an error.
Actual behavior
Getting an error message with a long backtrace.
Steps to reproduce
Start entering DiffviewOpen HEAD~1. The error shows up before finish typing HEAD.
