[Bug] Cannot upsert second column of questions with current behavior of load.ts

[zeke-emerson]

Is this a new bug?

• I believe this is a new bug
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

When I run npm start -- load --csvPath=test.csv --column=question2, I get the following error:

PineconeUnmappedHttpError: An unexpected error occured while calling the https://controller.us-east4-gcp.pinecone.io/databases endpoint.  index semantic-search already exists Status: 409.

After discussion with Roie, there should be a simple fix in load.ts that can properly check for the existence of the index and properly connect to the existing index to allow for the upload of the second column.

Expected Behavior

The npm start -- load --csvPath=test.csv --column=question2 command in the ReadMe executes without issue and the second column of questions is uploaded.

Steps To Reproduce

1. Clone the repository and execute npm run build.
2. Run npm start -- load --csvPath=test.csv --column=question1
3. Run npm start -- load --csvPath=test.csv --column=question2 and observe the error noted above.

On line 45 of load.ts, I changed the code to the following and it executes as expected:

  const indexList = await pinecone.listIndexes();
  if (!indexList.find((index) => index.name === indexName)) {
    await pinecone.createIndex({
      name: indexName,
      dimension: 384,
      waitUntilReady: true,
    });
  }
