Stream a PDF into a File

[Clive321A]

Hi, I'm trying to upload a file and then use it in an Assistant, the UploadFileAsync() throws a Object reference exception, document is loading ok, size in stream looks correct.

I tried with or without seeking the stream back to the beginning, just wondering if I'm doing this correctly, or off track.

                    FileStream document = File.Open(@"c:\temp\sample.pdf", FileMode.Open);
                    document.Seek(0, SeekOrigin.Begin);
                    OpenAIClient openAIClient = new("12345");

                    FileClient fileClient = openAIClient.GetFileClient();
                    OpenAIFileInfo pdfFile = await fileClient.UploadFileAsync(
                        document,
                        "sample.pdf",
                        FileUploadPurpose.Assistants);

Thank you for reporting this issue, @Clive321A ! Based on the callstack, this is likely a duplicate of the following: 🔗 https://github.com/openai/openai-dotnet/issues/84. As a workaround, try using version 2.0.0-beta.5 for now.

I have a PR to fix this issue here: 🔗 https://github.com/openai/openai-dotnet/pull/85. We will push an updated package soon.
