Using Open AI ResponsesClient and HostedFileContent produces corrupted files error

[KornelijusS]

As title states, when you add a file through HostedFileContent and pass it to ai as a message, the ai always responds with corruped file. The file is pdf tried with multiple files all of them produce the same answer. The files are uploaded through AIProjectClient.OpenAI.Files.UploadFileAsync. You can see the file inside microsoft foundry files, but using it through Agent Framework makes it corrupted for some reason.

Figured out that FileClient.UploadAsync is broken as uploading directly through rest api does work
