Unable to proceed further on the LangChain part of the notebook
P.S. I did install
pip install langchain-openai -U

llm = ChatOpenAI(temperature=0, model_name="gpt-3.5-turbo-1106")
chain = load_summarize_chain(llm, chain_type="stuff")
# Error occurs at the chain.invoke line of code below...
chain.invoke([Document(page_content=table_html)])

in chain.invoke line of code I get the error. I did create a new project key at

Error:
RateLimitError: Error code: 429 - {‘error’: {‘message’: ‘You exceeded your current quota, please check your plan and billing details. For more information on this error, read the docs: https://platform.openai.com/docs/guides/error-codes/api-errors.’, ‘type’: ‘insufficient_quota’, ‘param’: None, ‘code’: ‘insufficient_quota’}}
