Can you use the Submit Form as Zapier Trigger

Yeah, I tried that and I got an error.

I mentioned it in this topic - Geting errors when Zaps are triggered

I’ve tried setting it up on the submit as a custom action and on its own using the on submit Zapier options but I get the above error each time. I get the same error when I try to trigger the zap on a button so wasn’t sure if i’m doing something wrong or i’m trying to do something that can’t be done yet.
