Hi.

Could you show some code?
I had this error too while I was trying to implement an assistant with file_search.

I do:

• Create files with openai.files.create()
• Create vector store
• CreateAndPoll vector store files.
• Update assistant

 const fileData = await openai.files.create({
            file: fs.createReadStream("kit-idraulici.pdf"),
            purpose: "fine-tune",
        });

        let vectorStore = await openai.beta.vectorStores.create({
            name: "Test",
        });

        await openai.beta.vectorStores.files.createAndPoll(
            vectorStore.id,
            {
                file_id: fileData.id,
            }
        );

        await openai.beta.assistants.update(assistant.id, {
            tool_resources: { file_search: { vector_store_ids: [vectorStore.id] } },
        });

This works for me but I may have misunderstood your issue.

Ok this worked for me after changing these lines:
Changed const fileStreams = fs.createReadStream(filePath); to

const fileData = await openai.files.create({
      file: fs.createReadStream(filePath),
      purpose: "fine-tune",
    });

And instead of

await openai.beta.vectorStores.fileBatches.uploadAndPoll(
      vectorStore.id,
      fileStreams
    );

I have added this code

await openai.beta.vectorStores.files.createAndPoll(vectorStore.id, {
      file_id: fileData.id,
    });

Essentially changing from fileBatches (call like it's shown in the official docs) to files call and passing the fileData.id resolved my error.

But what if the purpose of my assistant is "file_search".
Following the Openai API documentation, I need to create a vector store with the new version of the library.
https://platform.openai.com/docs/assistants/tools/file-search/quickstart

// Step 1: Create an Assistant with File Search Enabled
const myAssistant = await openai.beta.assistants.create({
       model: "gpt-3.5-turbo-1106",
       instructions:
        "You are a customer support chatbot. Use your knowledge base to best respond to customer queries.",
      name: "Customer Support Chatbot",
       tools: [{ type: "file_search" }],
 });


// Step 2: Upload files and add them to a Vector Store
const fileStreams = ["file1.txt"].map((path) =>
    fs.createReadStream(path)
  );


  // Create a vector store including our files.
  let vectorStore = await openai.beta.vectorStores.create({
    name: "Customer queries Vector Store",
  });

  await openai.beta.vectorStores.fileBatches.uploadAndPoll(
    vectorStore.id,
    fileStreams
  );

and here is where the error appears

Thanks for reporting, we'll look into this soon.

Still getting the same error. Any update on the issue?

If you attach directly the file to the new thread, it works!

const knowledgeFile = await openai.files.create({
    file: fs.createReadStream("knowledge.txt"),
    purpose: "assistants",
  });

  const thread = await openai.beta.threads.create({
    messages: [
      {
        role: "user",
        content: "What can I buy in your online store?",
        // Attach the new file to the message.
        attachments: [
          { file_id: knowledgeFile.id, tools: [{ type: "file_search" }] },
        ],
      },
    ],
  });
