I've fixed it!

Changes to be done

Download latest packages for langchain

npm i @langchain/openai @langchain/pinecone @pinecone-database/pinecone

Imports

import { PineconeStore } from '@langchain/pinecone';
import { Pinecone } from '@pinecone-database/pinecone';
import { OpenAIEmbeddings } from '@langchain/openai';

Pinecone Initialization

Pinecone docs says "Instantiate a new Pinecone client, which will automatically read the env vars: PINECONE_API_KEY and PINECONE_ENVIRONMENT which come from the Pinecone dashboard"

const pinecone = new Pinecone();
const pineconeIndex = pinecone.Index(process.env.PINECONE_INDEX!);

so You just need to initialize it with keys in .env file

OpenAI Embeddings

This must be same for yours as well, incase if not write this code

const embeddings = new OpenAIEmbeddings({
      openAIApiKey: process.env.OPENAI_API_KEY!
});

TypeScript fix

Now your typescript error must be gone here

await PineconeStore.fromDocuments(pageLevelDocs, embeddings, {
      pineconeIndex,
      namespace: doc.id,
});

First of all, thank you very much for the help. I've tried out your instructions, but unfortunately, now there are other errors. Maybe you have another idea where the problem lies;

I'm sorry, I'm not really making the whole app. I was just watching Josh's video for learnings.
