Thread message attachment

[BlazejVaibro]

Hi,

I would like add file to attachment in thread message.

My Code

  List<Attachment> attachments = new();

  if (files != null)
  {
      foreach (IFormFile file in files)
      {
          await using Stream inputStream = file.OpenReadStream();
         
          FileUploadRequest fileUploadRequest = new FileUploadRequest(inputStream, file.FileName, FilePurpose.Assistants);
          OpenAI.Files.FileResponse apiFile = await _api.FilesEndpoint.UploadFileAsync(fileUploadRequest, cancellationToken);

          attachments.Add(new Attachment(apiFile.Id, Tool.FileSearch));
      }
  }

  OpenAI.Threads.Message message = new(
      content: text,
      attachments: attachments
  );

  await CancellThredRuns(thread, cancellationToken);
  try
  {
      MessageResponse messageResponse = await thread.CreateMessageAsync(message, cancellationToken);
      RunResponse run = await thread.CreateRunAsync(assistant, StreamEventHandler, cancellationToken);
      run = await run.WaitForStatusChangeAsync();
      var reposonseMessages = await run.ListMessagesAsync();
      return string.Concat(reposonseMessages.Items.SelectMany(x => (x.Content.Select(x => x.Text).ToList()).ToList()));
  }

Error from openAi

"CreateMessageAsync Failed! HTTP status code: BadRequest | Response body: {\n  \"error\": {\n    \"message\": \"Files with extensions [.csv] are not supported for retrieval. See https://platform.openai.com/docs/assistants/tools/file-search#supported-files\",\n    \"type\": \"invalid_request_error\",\n    \"param\": null,\n    \"code\": \"unsupported_file\"\n  "

I noticed that the files are added to the vector stored assistant, but I don't want to add them there. I want them to be added only to the messages in the thread.

How can I do that?

Files with extensions [.csv] are not supported for retrieval.

Has to be regular txt messages I guess. You could always use the vector stores endpoint to upload and vectorize it instead and use file id as well.
