Http headers not added to the HTTP Requests

[digitalhomeiot]

I m trying to do a HTTP GET Request

Whenever I execute the script it says "Request should have succeeded, but was '401 Unauthorized' "

I have set the basic auth and the required request headers, and when I try to capture the packet I see that the headers are not added to the Request.

Set Request Header Content-Type application/json
Set Request Header Content-Type application/x-www-form-urlencoded
Set Basic Auth xxx xxx
GET http://host:port

Can someone please help me on solving this problem
Thanks in Advance
