Describe the bug

I have been having challenges with Autogen framework for quite sometime now, I have followed YouTube tutorials, Autogen documentations, done the necessary installations and still get the same error _TypeError: 'NoneType' object is not iterable_. this is my codes I used, the app builds a folder named "coding", afterwhich the application breaks and then this error pops up.

Steps to reproduce

These are my codes

import os import autogen from autogen import AssistantAgent, UserProxyAgent

os.environ["OPENAI_API_KEY"] = "dummy_key"

llm_config_local = {"config_list" : [{ "model": "gemma-2-2b-it-GGUF/gemma-2-2b-it-Q4_K_M.gguf", "base_url": "http://localhost:1234/v1/completions", "api_key": None, "price": [0, 0] }]}

assistant = AssistantAgent("assistant", llm_config=llm_config_local)

user_proxy = UserProxyAgent( "user_proxy", code_execution_config={"executor": autogen.coding.LocalCommandLineCodeExecutor(work_dir="coding")} )

Start the chat

user_proxy.initiate_chat( assistant, message="Plot a chart of NVDA and TESLA stock price change YTD.", )

Model Used

LM server

"model": "gemma-2-2b-it-GGUF/gemma-2-2b-it-Q4_K_M.gguf",

Expected Behavior
