aider with ollama fails when generating a commit message

[yrobla]

Describe the issue

When a commit message is proposed for an specific file edit, we get error:
litellm.APIConnectionError: Ollama_chatException - Extra data: line 2 column 1 (char 437)

I debugged the issue and it was narrowed at the step when aider generates a commit message, using LLM, and sends a request like:

in send completion
{'model': 'ollama_chat/qwen2.5-coder:7b', 'messages': [{'role': 'system', 'content': 'You are an expert software engineer that generates concise, one-line Git commit messages based on the provided diffs.\nReview the provided context and diffs which are about to be committed to a git repo.\nReview the diffs carefully.\nGenerate a one-line commit message for those changes.\nThe commit message should be structured as follows: : \nUse these for : fix, feat, build, chore, ci, docs, style, refactor, perf, test\n\nEnsure the commit message:\n- Starts with the appropriate prefix.\n- Is in the imperative mood (e.g., "Add feature" not "Added feature" or "Adding feature").\n- Does not exceed 72 characters.\n\nReply only with the one-line commit message, without any additional text, explanations, or line breaks.\n'}, {'role': 'user', 'content': '# Diffs:\ndiff --git a/app.py b/app.py\nindex abc9ebf..230525e 100644\n--- a/app.py\n+++ b/app.py\n@@ -4,11 +4,3 @@ def hello():\n Returns a greeting message.

We have no token here"'}], 'stream': False}

Litellm fails directly, seems we are sending some malformed json.

Steps to Reproduce

Have this file:

@app.route('/')
def hello():
"""
Returns a greeting message. Checks for the presence of a GitHub token
and returns a specific message if the token is found.
"""
GITHUB_TOKEN="xxx"
AWS_ACCESS_KEY_ID="xx"
AWS_SECRET_ACCESS_KEY="xx/K7MDENG/bPxRfiCYEXAMPLEKEY"
GITHUB_TOKEN="xx"
if GITHUB_TOKEN:
return "Hello from Python 3.8 inside an EC2 instance running on Fargate, with a Github Token like this one in the code base!!"
else:
return "Hello, Mars! We have no token here"

Execute: aider app.py --model "ollama_chat/qwen2.5-coder:7b" --message "explain this app line by line"

and wait until the commit generation step
