Problem connecting to a url with http request node.

Question

request("https://" + username + ":" + password + "@api.twilio.com/2010-04-01/Accounts/" + username + "/Messages.json")

The above code in the HTTP request node gives me the following error:
1)
E 0:00:03.909 toint: Cannot represent (password)@api.twilio.com as integer, provided value is too big.
<C++ Error> Condition "integer > 2147483647 / 10" is true. Returned: sign == 1 ? 2147483647 : (-2147483647 - 1)
<C++ Source> core/ustring.cpp:1792 @ toint()
HTTPRequest.gd:20 @ onButtonpressed()
2)
E 0:00:03.912 _parseurl: Condition "port < 1 || port > 65535" is true. Returned: ERRINVALIDPARAMETER
<C++ Source> scene/main/httprequest.cpp:81 @ _parseurl()

Ive removed the username and password part and it successfully connected to the API,but it says I did not do authentication,so I used post method to pass in the authentication with the header as follow:

["username:password"]

but it still does not work.....It says the same thing...
Can anyone please explain how do I connect to twilio REST API with Godot with authentication?????
