Password Reset - Hide Web Services URL from error response

I am working on determining if there is a clean way to add a check to a breached database (HaveIBeenPwned) when performing a password reset. I created a web services connector that has the “Change Password” feature implemented, and is able to successfully return the results that I am looking for.

My challenge is the password reset exposes the Web Services URL in the Client UI when a password is selected that is compromised. Is there a way to suppress the URL and only show the response body?
