OpenAI Assistant can't run with a file

[zachary-nguyen]

Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangChain.js documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain.js rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

import { OpenAIAssistantRunnable } from "langchain/experimental/openai_assistant";
import { OpenAIFiles } from "langchain/experimental/openai_files";

const openAIFiles = new OpenAIFiles();
const file = await openAIFiles.createFile({
  file: fs.createReadStream(path.resolve(__dirname, `./test.txt`)),
  purpose: "assistants",
});

const assistant = await OpenAIAssistantRunnable.createAssistant({
  model: "gpt-3.5-turbo-1106",
  instructions:
    "You are a weather bot. Use the provided functions to answer questions.",
  name: "Weather Assistant",
  tools
});

const response = await assistant.invoke({
  content: "Please look at the weather data from the provided file and give some insights"
  fileIds: [file.id]   // This is the current payload required from the code
});

// Fix should be this
const response = await assistant.invoke({
  content: "Please look at the weather data from the provided file and give some insights"
  attachments: [{
                file_id: fileId,
                tools: [{type: "code_interpreter"}]
    }]
});

Error Message and Stack Trace (if applicable)

error: {
  message: "Unknown parameter: 'file_ids'.",
  type: 'invalid_request_error',
  param: 'file_ids',
  code: 'unknown_parameter'
}

Description

I'm trying to use an assistant to parse a file and provide some feedback on the data.
Getting the above error when trying to invoke the assistant

@zachary-nguyen Hello! I'm here to help you with bugs, questions, and becoming a contributor. Let's tackle this issue together.

To resolve the "Unknown parameter: 'file_ids'" error, you should adjust the structure of the invoke method call. The error indicates that the file_ids parameter is not recognized, and it seems like the correct approach is to use the attachments field instead. Here's how you can modify your code:

const response = await assistant.invoke({
  content: "Please look at the weather data from the provided file and give some insights",
  attachments: [{
    file_id: file.id,
    tools: [{ type: "code_interpreter" }]
  }]
});

This change aligns with the expected structure for handling file attachments in the invoke method, using the attachments array to specify the file_id and any associated tools ^[1].
