proxy not working on adding to session at the time of request

[White2001Offl]

Hi,
So basically if Proxies are added at the time of creating Session it works
but on sending request Like Get or Post it doesn't work

Using Proxy while creating Request in Session

proxyURL, _ := url.Parse("http://127.0.0.1:8080")
session := grequests.NewSession(nil)

res , _ := session.Get("https://api.ipify.org?format=json",&grequests.RequestOptions{
        Proxies: map[string]*url.URL{
		"http": proxyURL,
		"https": proxyURL,
	},
})
fmt.Println(res.String())

This above request gives my own IP

	Proxies: map[string]*url.URL{
		"http": proxyURL,
		"https": proxyURL,
	},
})
res , _ := session.Get("https://api.ipify.org?format=json",nil)
fmt.Println(res.String())
