null is passed as credentials when clicking on the link on the homepage

[slavaboiko]

when you click on the "HTTP Requests" link on the homepage, it takes you to the website to make a test HTTP call, but credentials are not populated and coming as null.

when clicking on the "How do I receive notifications" in the menu - everything works fine!
