ArgumentError: wrong number of arguments when copying stream

[madleech]

When request.env["rack.input"] is passed through to a Net::HTTP request as the body, copy_stream is called on it, which throws an exception:

 3.86s    error: Protocol::Rack::Adapter::Rack2: Reading HTTP/1.1 requests for Async::HTTP::Protocol::HTTP1::Server. [oid=0x2648] [ec=0x265c] [pid=1611996] [2024-08-21 11:22:02 +1200]

Ran into this when trying to stream request bodies to an S3 put request.
