Hi,
It is an expected result that you see "Javascript is required" warning when you test it in Postman because Javascript doesn't work on Postman and Outsystems reactive web app requires Javascript. However, your redirection is working actually. So, you redirected the user to the correct page successfully. You should see the HTML source code in the pretty or raw tab in the response as looking as below.

I would like to help you more if there are still issues in your case.
Please also let me know your aim for this kind of redirection.
Sincerely,
Necmettin
