the `Content-Type` header value. Should be specified if using a `fileBody` that is neither `Blob` nor `File` nor `FormData`, otherwise will default to `text/plain;charset=UTF-8`.
The duplex option is a string parameter that enables or disables duplex streaming, allowing for both reading and writing data in the same stream. It can be passed as an option to the fetch() method.
