TypeError: Cannot read properties of undefined (reading 'query') #1440

import { PineconeClient } from "@pinecone-database/pinecone";
import { VectorDBQAChain } from "langchain/chains";
import { OpenAIEmbeddings } from "langchain/embeddings/openai";
import { OpenAI } from "langchain/llms/openai";
import { PineconeStore } from "langchain/vectorstores/pinecone";

const pinecone = new PineconeClient();
await pinecone.init({
   environment: process.env.PINECONE_ENV,
   apiKey: process.env.PINECONE_SECRET,
   namespace: process.env.PINECONE_NAMESPACE
});

const index = pinecone.Index(process.env.PINECONE_INDEX)

const vectorStore = await PineconeStore.fromExistingIndex(
   new OpenAIEmbeddings(),
   { index }
);

const model = new OpenAI();
const chain = VectorDBQAChain.fromLLM(model, vectorStore, {
   k: 1,
   returnSourceDocuments: true,
});

const response = await chain.call({ query: "What is Pinecone and how does it work?" });
console.log(response);

This code keeps returning the following when I run it:

I am using "langchain": "^0.0.84", within a Nextjs 13 api route and have played around with it to no avail. If I am missing anything please let me know, thanks!
