Sign up returns "isauthenticated"=False and network error with weweb/xano

I am new to App building.
I have the standard sign in and signup page in weweb. Xano auth plugin configured to what I think is right, videos are outdated so it was difficult to figure it out.
Whenever I do a signup or login(when I manually enter details in xano) I get this network error and the “isauthenticated” = false.
I have no idea how to fix it or whats wrong. This doesnt happen in the documentation or videos.
Does anyone know what this is?

I have some more details if this helps at all.
I have been talkign with Xano, they said the data is coming in on their end so it has to do with something on the weweb side.

it seems as though the error is “user already exists” duplicate data error.
there is definitely not existing data

has anyone encountered this?
I am totally stuck
