Hi Rahul,
Thank you for this wonderful project and I'm excited to play around with it.
I have Installed Ollama and run ollama run zephyr in my terminal. When I running extract_graph and set regenerate=True, I get the following error:

An error occurred: 502 Server Error: Bad Gateway for url: http://localhost:11434/api/generate

ERROR ### Here is the buggy response: None

I turned off the system proxy and set the following in code:
proxies = {
'http': None,
'https': None,
}
with requests.post(url, json=payload, stream=True, proxies=proxies, verify=False) as response:

and the problem was solved
