Additional context
Add any other context about the problem here.

I searched similar problems and fixed problem manually. https://community.openai.com/t/error-with-openai-1-56-0-client-init-got-an-unexpected-keyword-argument-proxies/1040332/24
The problem is version of openai and httpx.

• I update openai version in chatbot_api/pyproject.toml.

• "openai==1.7.2" --> "openai==1.55.3"

• I update httpx in requirements.txt

• httpx==0.26.0 --> httpx==0.27.2

Then, it works fine!!

I think it would be good to update this later.
Thank you.

Start in langchain-rag-app/source_code_final and inspect chatbot_api/pyproject.toml and requirements.txt for the OpenAI and httpx dependency versions. Rebuild with docker-compose up --build and confirm that chatbot_api starts without the reported Client.init() error.
