Thanks Stuart. My bad :( I had a body parser handler in the
request/response chain in order to do schema validation on body against
swagger specification and it consumed the body stream on the proxy server.
Is there a way I can consume the body and put the body stream back so that
other downstream handler can still parse the body if needed?

This looks really odd. It looks like the client request is expecting
there to be a request body, however the server request thinks the
request is finished and there is no request body available. Is it
possible an earlier handler is reading the request body so the proxy
handler can't access it?
