I am trying to upload a file using the OpenAI Java SDK and encountered an issue where the request fails when using InputStream, but succeeds when using Paths.get().

Use Code

public String uploadFile(MultipartFile file) { FileCreateParams params = FileCreateParams.builder() .file(file.getInputStream()) // Using InputStream .purpose(FilePurpose.ASSISTANTS) .build(); FileObject fileObject = openAIClient.files().create(params); return fileObject.id(); }

When using InputStream, the following error occurs:

400: OpenAIError{additionalProperties={error={message=The browser (or proxy) sent a request that this server could not understand., type=server_error, param=null, code=null}}} 

However, when I use Paths.get() instead, the request succeeds without issues.

Is this an expected behavior, or am I incorrectly using the SDK?
