I always get this error when I run add_documents from Langchain PineconeVectorStore. I have the latest versions of pinecone_client and langchain_pinecone libraries.

Hi @gpt and welcome to the Pinecone community forums!
Thank you for your question.
Please tell us the exact versions of each library you’re running.
Please also see our official LangChain guide and try using that example code first.
