Redirect on Sign up form not working

Hello i need help.
I am new to wappler but beginning to get a hang of it. I need a help tho.

I found this tutorial by @Hyperbytes on https://www.youtube.com/watch?v=ZIOJdbfxZdI&t=134s
about creating a user. I have followed every step and it works but when i hit the submit button, it creates the user in database but does not redirect to the success page. Rather it redirects to this URL http://localhost/firstproject/dmxConnect/api/register.php

Kindly help please.
