Why do you need a BytesIO object. You get whatever Storage.open() makes which could be something from S3 or disk etc
sorry i worded it wrong, what im trying to do is send that file to the chatgpt for analysis right now what im doing is ```py # file is the FieldFile object file.open() x = file.read() message_file = client.files.create( file=file.read(), purpose="assistants" ) file.close()``` but i get an error saying ``` Invalid file format application/x-empty. Supported formats: "c"```
