I still have this error in the latest version (main).

Why is the error ouput still showing Aider version: 0.83.1? I am on the latest - pip install shows "Successfully installed aider-ce-0.87.14.dev62" - I am a bit confused about the versioning.

Stuck on aider-ce-0.87.14.dev52 which for me is the last working version.

I have been able to get this configuration to work on 0.88.4. 0.83.1 would actually be Aider main since I forked at the 0.86.0 version of the main repo, so I am assuming you meant on 0.88.3 of aider-ce where you were experiencing this?
