Files created with client.Files.New() don't have names. Impossible to use them on vectorStore.

[ThadeuMelo]

I'm trying to push some files and later use them on vectorstore assistants.
However, I can't add the files to VS because it rejects the names as not supported.

"{\n \"message\": \"Files with extensions [none] are not supported for retrieval. See https://platform.openai.com/docs/assistants/tools/file-search/supported-files\",\n \"type\": \"invalid_request_error\",\n \"param\": \"file_ids\",\n \"code\": \"unsupported_file\"\n }"

Checking the files created with this code.
I noticed that all of them are named 'anonymous_file'

content, err := os.ReadFile(config.FilePath + filename) // the file is inside the local directory if err != nil { fmt.Println("Err") } file, err := client.Files.New(context.TODO(), openai.FileNewParams{ File: openai.F(io.Reader(bytes.NewBuffer([]byte(content)))), Purpose: openai.F(openai.FilePurposeAssistants), })
Is that expected behavior?
I'm missing something?

Thanks for bringing this up, try the solution in #91. We'll look into a better solution for the next launch too.

In case it's helpful for anyone, I wanted to share a full solution here.

@jacobzim-stl FWIW, I think the biggest footgun is that it's not quite clear how to solve it based on the error message or the typings, so I think an updated example would do wonders here. I think the API design itself could be improved, but it definitely works as-is. It could just use better guardrails since (IMO) you shouldn't be able to upload an anonymous file to the assistants API since it can't really be used.

#150 specifically had the information that fixed this for me (use the openai.FileParam struct).

Here's a full example (also available at this gist):

package main

import (
	"bytes"
	"context"
	"io"

	"github.com/openai/openai-go"
)

func main() {
	client := openai.NewClient()

	s := "This is just random context"

	file, err := client.Files.New(context.TODO(), openai.FileNewParams{
		// IMPORTANT
		File:    openai.FileParam(io.Reader(bytes.NewBuffer([]byte(s))), "context.txt", "text/plain"),
		Purpose: openai.F(openai.FilePurposeAssistants),
	})
	if err != nil {
		panic(err)
	}
	vs, err := client.Beta.VectorStores.New(context.TODO(), openai.BetaVectorStoreNewParams{
		Name:    openai.F(" Vector Store"),
		FileIDs: openai.F([]string{file.ID}),
	})
	if err != nil {
		panic(err)
	}
	_, err = client.Beta.Assistants.New(context.TODO(), openai.BetaAssistantNewParams{
		Model:        openai.F(openai.ChatModelGPT4o),
		Name:         openai.F("Random Assistant"),
		Instructions: openai.F("You're a helpful assistant."),
		Tools: openai.F([]openai.AssistantToolUnionParam{openai.FileSearchToolParam{
			Type: openai.F(openai.FileSearchToolTypeFileSearch),
		}}),
		ToolResources: openai.F(openai.BetaAssistantNewParamsToolResources{
			FileSearch: openai.F(openai.BetaAssistantNewParamsToolResourcesFileSearch{
				VectorStoreIDs: openai.F([]string{vs.ID}),
			}),
		}),
	})
	if err != nil {
		panic(err)
	}
}
