failed to WebSocket dial: response body is not a io.ReadWriteCloser: io.nopCloserWriterTo

[ryebrand]

In the dial method, I got this error "failed to WebSocket dial: response body is not a io.ReadWriteCloser: io.nopCloserWriterTo". There was an error converting the resp returned by the handshakeRequest method to io.ReadWriteCloser.

Not sure what happened here. Can you trace net/http to figure out why you're getting a nopCloserWriterTo?
