I get this error when launching aider in a git report that has multiple React project

aider --model ollama/deepseek-coder-v2

If I launch it with --no-git, no error

$ aider --no-git --model ollama/deepseek-coder-v2 ─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── Warning for ollama/deepseek-coder-v2: Unknown context window size and costs, using sane defaults. Did you mean one of these?

• ollama/deepseek-coder-v2-instruct
• ollama/deepseek-coder-v2-lite-instruct For more info, see: https://aider.chat/docs/llms/warnings.html You can skip this check with --no-show-model-warnings

Proceed anyway? (Y)es/(N)o [Yes]: y
Aider v0.56.0 Model: ollama/deepseek-coder-v2 with whole edit format Git repo: none Repo-map: disabled Use /help for help, run "aider --help" to see cmd line args Note: in-chat filenames are always relative to the git working dir, not the current working dir.

But repo-map is disabled and I want to enable it. Now that issue might be independent.

[geraldthewes]

Sounds like the same issue as ticket #296 from last year

[geraldthewes]

Am I reading #292 correctly that basically aider (because of gitdb) only supports older versions of git and is basically not usable on any modern system? I'm surprised this is not a more important issue or am I missing something?
