After form submission redirect to 404 error page

I’m not a professional web designer. Just a personal project.
When I submit a form on my website instead of getting a success message it takes me to the 404 error page.

It seems like that I don’t have a success page, How do I add the success page?

Submit Button Settings are set to:
Button Text> Submit
Waiting Text> Please wait…
Redirect URL> /success
Action> webflow default
Method> POST ( I also had it as GET )

PLEASE HELP I’M WORRIED

Thank you guys
