niksis02 0972af0783 fix: fixes the nil body reader panic.
Fixes #1418

If neither the `Transfer-Encoding` nor the `Content-Length` headers are provided in chunked uploads, **fasthttp** assumes there is no request body and sets the request body reader to `nil`. This leads to a panic in the auth reader when it attempts to read the body.

The fix ensures that if the request body reader is `nil`, it is overridden with an `empty reader` to prevent panics.
