AttributeError: 'NoneType' object has no attribute 'create'

Checked other resources

[X] I added a very descriptive title to this issue.
[X] I searched the LangChain documentation with the integrated search.
[X] I used the GitHub search to find a similar question and didn't find it.
[X] I am sure that this is a bug in LangChain rather than my code.
[X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

model = OpenAI(model_name=model_name, verbose=True)
chain = ( { "context": get_context, "extra_instructions": get_instructions, "question": get_question, } | prompt | model | StrOutputParser() )

    result = await chain.ainvoke(input_text)

Description

This worked fine in older versions of langchain and openai, but when updating to later versions, I now get the above error. Any suggestions are greatly apprecaited.
