Proxy environment variables are handled by the net/http default client and the http.Transport.
See
https://pkg.go.dev/net/http#ProxyFromEnvironment
and
https://pkg.go.dev/golang.org/x/net/http/httpproxy#pkg-overview

The client runtime normally uses the http.DefaultTransport (but in the case of specific TLS config).

So this is quite weird. go-openapi and the generated client do not tamper with proxy settings.

You can alway override the proxy behavior using the Proxy field of a http.Transport passed as roundtripper .to the client runtime.
