Registration creates user in auth0 DB but not wordpress DB

Previously noted here, looks like no folllow-through:

Auth0 doesn't create Wordpress user after successful sign up

Sign up is working ok, but if the user is not yet available on the Wordpress database, it does not create the users there. How do I fix this? Login and Sign up using existing Wordpress users are fine though. I need to know how I can debug this. I am trying to fetch it using wpa0_user_created and auth0_user_login but I can’t seem to debug it.
