Not able to upload file from client

API
1

I’m struggling to upload a file directly from the client. In the documentation the create function uses fs.createReadStream(filePath) to create a stream of the file (which uses the file system) but I need to send the file selected by the user via the file select input field so the file never goes to the file system. So I send the file as FormData() to the endpoint and then try to create a read stream of it but I get this error that it does not support it. I have also tried to directly set the Buffer i get from the client to the file key in the create object but then I get an error saying that the value transmitted exceeds the capacity limit even though the file is not too big (it is 43KB and the limit is 512MB):

The buffer directly:

const file = await openai.files.create({
            file: fileData // Buffer from the client,
            purpose: "some purpose here",
        });

Creating a stream of the buffer:

      const stream = Readable.from(fileData); // fileData is the buffer from the client

        const file = await openai.files.create({
            file: stream, // Pass the stream for the file upload
            purpose: "some purpose here",
        });

Is there a workaround / fix to this? Or should I write the file to a temporary folder and then create the read stream from there with the fs.createReadStream() or what is the best practise?

Hi Nicolas,

Yes for me, the best practice is like below.

const addedFile: FileObject = await openai.files.create({
    file: fs.createReadStream(file.path),
    purpose: "assistants",
});

You should pass file.path as a parameter, not buffer or file itself.
