Version Compatibility Issues with node @langchain/core and @pinecone-database/pinecone

Support

I upgraded node SDK for pinecone-database/pinecone to 3.0.2 and I am having weird compatibility build error. What is a recommended set of related packages that are compatible with it?

Versions:

"@langchain/community": "^0.0.57",
"@langchain/core": "^0.2.31",
"@langchain/openai": "^0.2.10",
"@langchain/pinecone": "^0.0.9",
"@pinecone-database/pinecone": "^3.0.2",

Error:

Argument of type 'VectorStoreRetriever<PineconeStore>' is not assignable
 to parameter of type 'VectorStoreRetriever<VectorStoreInterface>'.
  Property '_streamEvents' is missing in type 'VectorStoreRetriever<PineconeStore>' but 
required in type 'VectorStoreRetriever<VectorStoreInterface>'.

CODE:

  const retriever = vectorStore.asRetriever({
    callbacks: [
      {
        handleRetrieverEnd(documents) {
          resolveWithDocuments(documents);
        },
      },
    ],
  });

  // *** offending line:
  const chain = await makeChain(retriever);

WHICH CALLS:

export const makeChain = async (retriever: VectorStoreRetriever) => {

I appreciate any help with this. Node v.20.

I figured it out. Had to change:

import type { VectorStoreRetriever } from ‘langchain/vectorstores/base’;

to

import { VectorStoreRetriever } from ‘@langchain/core/vectorstores’;

The migration tool didn’t catch that.
