Vuejs Ajax call aways fires error function - php

Question

Hey Everyone so I am trying to make a vueapp that makes an ajax call to a php page. On that php page I am running a few mysql statements the most important of which is a insert statement. if that page ajax call is successful and the insert statement runs successfully I want to redirect a page. If the ajax call or the insert statement fails or the user exists I want to redirect them the same page just render the page diffrently based on the result. I've tried doing it with sessions however when i try to use the ajax error function it fires everytime even when its successful. I know this as I get an alert error. But than when it goes to the result.php page I get success. I dont understand. Any help would be great! Heres the code for the vueapp (signup.php)
<?php ob_start();
session_start();
include('head.php');
include('header.php');
?>
<div id="signUpFormContainer">
