Hi, thank you for creating this Tool.

I think the model parameter recently broke, or they changed the model names.
I was using ChatGPT with model="gpt-4" like one week ago and it worked just fine, however i just found that using model="gpt-4" returns now.

I assume there was a change from OpenAI, a list of all models would be usefull, but i have no idea how to get them.

from WebChatGPT import ChatGPTbot = ChatGPT(    "[...]",    model="gpt-4")response = bot.chat("hello")print(response)

File[....]utils.py:243, in get_message(response)
241 # print(json.dumps(response,indent=4))
242 assert isinstance(response, dict), "'response' should be of 'dict' data-type"
-->243 return response["message"]["content"]["parts"][0]

TypeError: 'NoneType' object is not subscriptable

When i read the post request from OpenAI it still sends `{"server_request_id":"84b130e05d9a6a73-TXL","model":"gpt-4","preflight_time_ms":20,....}`I am pretty sure that there is no response returned, but i am not sure how to fix it.
