How to send back validation errors from a Make automation flow to Softr?

Hello,

I have a form in Softr. When I submit it, I invoke a Make automation and it has multiple routes. First route has a filter that checks for distinct email address, if not, I’m trying to send back a webhook response. Doesn’t seem to work, as in, I don’t see any message that comes back. Any pointers would be of great help. Thanks!

Here is my Make flow and my webhook response.

Note: The html is just a test html
